Episode 1
Introduction of Tae
Tae begins his day in his new dormitory room and a telephone conversation with his mother encouraging him to enjoy his first day of university and make lots of friends. After his phone call, Tae takes his keys from the key rack by the door and leave enthusiastically to start his day.
Tae attends classes and begins to make new friends. His weeks are filled with classes and studying and most nights he get back to his room exhausted.
One afternoon, there is a class postponement and Tae decides to return to his room to rest due to the exhaustion he's been experiencing since he started.
On the return to his room, he enters to discover a man wrapped in a towel, drying his hair with another towel exiting his bathroom. They make eye contact, both startled. Tae stutters an apology and quickly leaves the room. Back in the corridor, he looks around and notices he had, in fact, entered the correct room. Unsure what happened, Tae tentatively reenter the room and after a cautious glance around, discovers there is no one . Confused, Tae considers it a figment of his imagination due to being exhausted and collapses on the bed.
Introduction of San
San stared at the boy standing in the door way, startled he so brazenly entered his room. Before he could do or say anything the boy stuttered and immediately left the room. San went to the door and turning the door handle, found the door locked. Confused he quickly dressed, then unlocked the door and entered the corridor. The corridor was silent and San checks the door handle from the outside, confirming it worked fine.
The following day, while on his way to class San tells his best friend, Second what happened the day before. Second laughs and teases San. Second suggests it might be someone from an adjoining room who make a mistake, but San explain he knows who the neighbouring students are are this person was unfamiliar to him.
Changing the topic, Second asked about San's grandfather. There's some issues with his grandfather health and San is worried and intents to visit that afternoon.
In the evening San visits his grandfather in hospital and his mother and aunt are also there. His grandfather tells them he plans to change his will to make San the sole benefactor San, given he is the only male descendent. San explains he doesn't need grandfathers money but grandfather insists San take on the family responsibility from both his mother and aunt.
Outside the hospital room, San again tells his mother and aunt he isn't interested in grandfathers money or business. Both women are concerned by their father sudden insistence in changing his will. Mother tells San not to concern himself and she and aunt will work something out.
When San leave mother and aunt are worried about their father mental state and decide profession help made need to be sort to determine if their father is in his right mind.
Episode 2
Grandfather meets with his lawyers in the hospital room to discuss San being included in his will. The lawyers explains grandfather's health is improving and he should consider updating his will once he's out of the hospital. But grandfather has put a lot of thought into it and want's to ensure everything he's created will be passed down to his remaining male heir. The lawyers agrees to arrange the documents and leaves the hospital room.
Alone in his room grandfather then asks for San's forgiveness but its the only was to ensure the future of their businesses.
San meets with his mother after afternoon classes. She explains grandfather is determine to change his will and the reason being him being the last male heir. San explains his dislike in this and believe his mother and aunt do a great job running the business, that he's unsure why he must be dragged into it. San's mother tells him to worry about classes and leave the rest with her. San's mother leave him with homemade sweets from the main house and tells him to take care.
On his way back to his room, San comes across his friends, who had been out for a meal together. They were heading to another place for dessert and ask San to join them. San has a lot on his mind and declines and as an afterthought offers the homemade desserts his mother gave him. They ask if his mother made them and San assumes she did. His friends early agree to take the sweets asking if San wanted to join them but San refuse and leaves them to return to his dorm room.
Tae stands in front of the dorm room early evening after study group finished late, tentative about opening the door. But with a shake of his head, he unlocks the door and enters. The room is empty but he immediately notices the lamp of desk is on. Coming to the desk, keys still in hand, Tae drops them on the desk asking himself if he'd left the lamp on that morning. But with the shake of his head, he didn't recall tuning it on. Taking his mobile telephone out of his pocket, Tae went to put his phone on charge when he realised the lamp was where the phone charger should be.
Confused, he does a quick search for the phone charger on the desk, while moving the lamp back to the other side of the desk. Not finding the charger and somewhat suspicious, Tae once more thought about whether his room was haunted. The thought terrified him and quickly Tae grabs his towel hanging over the back of the chair and goes to the bathroom. As the bathroom door closes, the dorm room opens and San walks in.
San places his room key on the table and notices the lamp on the other side of the table. Confused, he looks around the room, remembers the face of the person who entered his room previously and also considers maybe his room is haunted. He slowly picks up the lamp and places it back where it belongs. He looks around for his towel and can't find it. He was sure he left in hanging over the chair but unable o find it, removes a clean one from the cupboard before heading to the bathroom slightly confused by the missing towel.
New note - Tae's bag?? Gemini finds the bag beside the desk. Leave bag outside room. That's where Tae finds it.
At that moment the bathroom door opens and Tae exits only to stop startled at the sight before him.
His phone charger is now back on the desk, where only moment before it was not. Suspiciously, he glances around the room, then notices his towel hanging over the back of his chair. More suspiciously, he glances at the towel around his waist, then back the towel on the chair. Rubbing his hair in confusion, he heads to his cupboard for clean clothes.
The following day, during the lunch break between classes, Tae explains the situation with the lamp but doesn't mention the part about the mysterious man in his room, to his friends. They discuss the possibly of it being haunted and Tae is reluctant to listen to their words and quickly forces them to stop discussing it.
In another part of the campus, San sits waiting for his friends to arrive only to find Second arrives. He explain those who went out to eat the evening before ended up with food poisoning and couldn't attend classes. San mentions how he was going to go but instead met up with his mother and Second also explains he had tutoring which was why he didn't attend.
Second asks about his meeting with his mother and San brushes over the topic of grandfathers will. The friend asks if there might any problems with his cousins, given they are all female. San shrugs. He gets one well with his cousins but he doesn't know if this issue will create problems between them.
On his return that afternoon, Tae hesitates to enter his room but after scolding himself he puts the key in the lock and opens the door. At that moment San, sitting on the chair by the bed, reading a book, looks up as the sound of his door being unlocked and opened.
Tae enters and as he goes to put his room key on the key rack he notices it's missing. His hand pauses mid-air and his body then involuntarily shakes as his begins to think about ghosts again. Shaking his head, he murmurs to himself about ghost not existing. Then from the other side of the bed, a voice responses with, "Who are you. And why are you in my room." Tae is startled and he turns to see San rising from the chair, his stare piecing Tae's as he approaches. Tae panics, stuttering the word "ghost", then stumbles and begins to fell backwards.
San immediately comes forward and grabs Tae around the waist, stopping him from falling. It's only then do both stare at each other, realising both are real people.
Episode 3
Tae sits on the bed, staring at his hands, shaking his head, while murmuring again about ghosts.
San then speaks up. He's leaning against the desk staring at Tae on the bed. "If anyones the ghost, it's you."
Tae's head shoots up to look at San. "Me, the ghost. No. This is my room. How can I be the ghost."
"Your room." San replies. "No. This is my room."
Tae is confused even more and San can't make any sense of any of it.
"How did you get into my room." San asked.
After some demanding and some what accusing discussion, San is able to prove it's his room given the various items around the room. When Tae realises it's not his room, he's quite confused. Tae stands and looks around the room. The desk and lamp are the same. The cupboard door has the same sticker as his, and the chair in the corner is the same. But that is where the similarity stop. The accessories are different. Tae realised it is indeed not his room and yet, the familiarity of the room tells him otherwise.
At that moment, Tae glances at the desk and see the study books with the previous years date on it. Tentatively, he picks up the study book and looking at San asks why he's using the book from the previous year. San frowns in confusion and asks why Tae would think the book is from the previous year when the book is, in fact, that year. Tae looks back down at the book and his hand begins to shake. Tae then drops the book back on table and pushing past San, rushes out the room.
Startled, San regains his balance and rushes out to follow. But as San enters the corridor, it's empty. Startled by this, San looks back into the room, confused about what happened.
Tae rushes down the exit stairs of the building and escapes outside. Once out of the building Tae stops and catches his breath. Glancing back at the building he has no idea what happened. Should he call his friend but what would he tell him. But he knew he couldn't return to his room on his own, so he calls First.
Back in the corridor Tae stand with his best friend, First. Tae explains what happened and First is sceptical and humours Tae and Tae knows his friend is making fun of him. Tae slowly opens the door as First barges in before him. Tae, startled, tries to stop him but as he enters discovers the room is his. He stares at the key rack on the wall and as he walks in further sees his plush toy on the chair. First is sitting on the bed, staring up at Tae asking to see the ghost.
Tae is confused and doesn't know how to explain. He sits beside his friend on the bed and explains he knows what he saw.
San sits with Second during lunch break.
They too are discussing the 'ghost' in San's room. Second questions why this 'ghost' would suspect the book he was using was from the previous year and they conclude maybe this person isn't a ghost but someone from the future. San doesn't believe it and thinks Second are crazy. But it's Second who think San is the crazy one. Second suggests if it happened again, find out the date this 'ghost' has come from, and then determine what is actually going on.
In the afternoon after classes, Pear, San's first oldest cousins, turns up unannounced at the university to see him. She tells him about knowing about grandfathers will and how it's frustrating that in this day and age he would consider a male heir more important that the achievements of the rest of the family. She apologies to San, explaining she wasn't looking down on him. But she and her sister, who are both many years older than San, been working for the family business for a long time and made many great achievements. They didn't want their effects to be ignored. San is sympathetic. He understands and doesn't want to be involved. He suggests he will talk with their grandfather again and try to get him to change his mind. As she leave, she hands San homemade sweets from the main house. San thanks her and they depart.
Tae paces the front of his dorm room, while First stands with his arm crossed over his chest against the wall opposite the door, watching Tae. After a short time, First rolls his eyes and snatches the key from Tae. Tae protests but First unlocks the door and enters the room. Tae remains in the corridor, reluctant to enter. The friend looks around the room and looking back at Tae holds out his hands and explains no ghost are present.
Tae is staring at the desk, fear on his face, as he slowly raised his hand and points to the desk. First turns to look and on the desk is a plastic bag. First picks up the bag and looks inside. "Sweets" he tells Tae.
Tae one shakes his head and relies, "Not mine."
First again rolls his eyes and comes back out to the corridor handing the bag to Tae, who refuses to take it. The friend reaches into the bag and pulls out the sweet and give it a sniff. He offers it to Tae how refuses and steps back, explaining, he'd never seen them before. The friend find this weird and to prove the sweet is real take a bite and explains it is delicious before taking another bite. Tae profusely shakes his head refusing to touch the sweets.
First shrugs and tells Tae there is no one in the room. Tae looks past First and slowly stepping past him, enters the room. The key rack is on the wall and the lamp is where it should be. Tae lets out a sigh of relief. First stands in the doorway and Tae tells him he can leave and to take the sweets with him. He wants nothing to do with anything strange in his room. His friend's expression shows he doesn't believe Tae and thanks his from the sweets before leaving. Tae closes the door and leaning against it asked himself how the sweets got into his room. Shaking his head, Tae grabs his towel from the back of the chair and enters the bathroom.
The sound of the shower is heard, and them turns off, the bathroom door open and steam exits the room and San walks out. The first he notices as he looks up is the sweets missing. "What the.... I'm sure I left them there." San checks the desk and around the room but no matter where he looks the sweets had definitely vanished.
Episode 4
Over the weekend, San visits his grandfather to discuss the will but discovers the changes have already been made. With San becoming sole benefactor. San is reluctant to argue with his grandfather and returns to the main house to discuss with his mother. On his arrival he finds his aunt instead. He tells her he doesn't want the responsibly of the ownership of the business given his aunt and daughters are the reason the business has been successful over the years but he doesn't know what to do.
His aunt understands and tells San she and his mother are trying to understand what's going on and that he shouldn't concern himself. But San knows grandfather is not well and ask if if grandfather does pass, he could relinquish his right to the family business. Aunt agrees that could be done and suggests she will discuss it with his mother and the lawyer and speak to him again once they know what is best to do.
Aunt meets her sister at the office and tells her she saw her son at the main house. Mother is worried for San and ask her sister what they can do. Aunt mentions meeting with the lawyer and coming up with a plan should their father die and San inherits everything. They both agree they can not do anything.
San is about to enter his dorm room, when his phone rings and he sees it's his mother. He answers the phone as he enters the room, closing the door behind him. Greeting her. His mother suggests they meet up the following day and San removes his bag from his shoulder and goes to throw it on the bed when his comes to a stop, bag failing in the air still clenched in hand, as he stares at the man sleeping in his bed.
San's mother voice brings him back to the fact she's in the phone. He tells her he'll meet with her and says he has to go. Hanging up the call, San slowly lowers his outstretched arm dropping his bag at his feet as he stares at Tae in his bed. But them suddenly came to realise it was not his bed. The blue bedding of his bed was replaced with yellow and the plush on the chair was not his. Coming further into the room, San notices the cupboard and the familiar sticker but there were clothes draped over the half open doors. As he glances at the desk beside him, he saw the lamp on the other side of the desk and a mobile phone changing where the lamp should be. Text books were stacked on the desk, the date of these book showed the following year.
San picked up the top book and looked at it. He opened the cover and saw the name of the owner in the book. San glanced at Tae sleeping in the bed, then closed the book in hand and gently placed it back on the others. He was sure it was his room but it wasn't his room. A memory of the conversation he's had with Second about time travel entered his mind. But he shook his head at the impossibility. And yet, the room wasn't his, that he knew. Slowly, San made his way toward the bed and slowly lowers himself to be kneeling beside the bed to stare at the face of the sleeping Tae.
Tae sleeps deeply, unaware of the intruder, as San unconsciously reaches out and brushes the hair away from Tae's eyes to get a better look. As he holds Tae's hair off his face, San realised what he's doing and immediately snatches back his hand. Glancing around the room once more, San rises and doesn't know what to do. Stepping back he grabs his bag and leaves the room. In the corridor, he pauses as he closes the door behind him and stares at the room number. It's definitely his room but nothing makes sense. Pulling out his phone he calls Second and sits down beside the door to wait.
When Second arrives, San get up and explains to him what happened. Second is sceptical but also interested, questions San. After some discussion, Second suggests they enter the room together. San unlocks to door and they enter. Only to discover it's San's room. San is confused. He know's what he saw. He stares at his hand and still recalls the texture of the Tae's hair he'd only touch moments before.
Second pats San's back and suggest if it happens again find out if he has a name. It's then that San remembers the name he saw in the book and tells his friend. His friend tells San he will enquire around and see if that person exists. San then explains about the year on the book and that it was from the future. His friend realises that person may not be at the university yet if he was indeed from the future but would still make enquires and see if that person did exist.
San questions why Second believes him. Second explains if this makes his friend crazy he would be crazy with him. San half laughs and thanks Second for believing him.
Tae wakes late in the afternoon after a late night playing games online. Stretching, Tae gets up to use the bathroom and steps on something soft underfoot. Tae lifts his foots and stares at the cute little character lying on his floor before picking it up. The clasp that should have the clip was missing and Tae wondered how it had gotten in his room. He then suspiciously looks around. Tossing the keychain on the desk, Tae uses the bathroom, then taking his phone from the charger returns to bed. After scrolling through his socials, he ring First but only gets his vice mail. Thinking his friend might also be asleep he send a message for him to call him once he's awake.
It was much later that night that First called Tae. First voice was hoarse and he went on to explain to Tae he'd been extremely ill and was in hospital. Tae asked if he needed him there and if there was anything he could do. First told Tae to not come, that whatever he had might be contagious. Tae agree to stay away but made First promise to contact him as soon as he was back in his room so that he could take care of him. First agreed and said he should be discharge the following day.
Tae arrived at First's room with food but First was still unwell and had no appetite. Did First know what he had, Tae enquired. First said it was some sort of food poisoning, maybe from the sweet's he'd eaten. Tae asked if he'd eaten the all in one go, to which First said he had. But First didn't think it was only the sweets that made him sick and the hospital detected a various in his system and that is was a series of unfortunate circumstances.
Tae ate food the food he bought as First lay in his bed still feeling miserable and told First about the cute keychain he'd found on the floor of his room. First asks to look at it and Tae fishes it out of his pocket and hands to First. He mentions it looking like one of the special series keychain from a famous eatery near their university. First suggest when he is better, they go together and ask as the keychains are limited edition so they might know who the owner is.
After class, Tae and First made to the eatery mentioned over the weekend. Tae asks if First is feeling better and they can leave the visit to another time but First is better and they head to the eatery. However, on their arrival they discover the special for that keychain was for the previous year with only 20 being issued. The staff couldn't tell them who it was given out too.
