Titles that open with I
I is dominated by first-person titles: "I Became…", "I Married…", "I Was Reborn…". That voice puts you in the driver's seat of a second chance or a sudden rank. It also tempts authors to explain every feeling. Sample two chapters and see whether the narrator acts or only comments.
Rebirth-in-the-title does not guarantee a clever revision of the first timeline. Some books restart and then repeat the original mistakes for hundreds of chapters. Completed I-titles are easier to judge because you can see whether the second life actually diverged.
This is a title index, not a ranked list. Reading guides and categories are better when you want a story type instead of a letter.
