A list of must read mangas that are Isekai or about Reincarnation

As the title suggests: This is another list of Transmigration or Reincarnation stories BUT as manga(japanese comics) or webtoon. My general genre are: Romance and Female Protagonist. Though, yes, this list will more or less be of the fantasy(Transmigration/Reincarnation) side. *hehe

WARNING SPOILERS FOR THE GAME DANGANRONPA DanganRonpa IF an AU written by Ryogo Narita! This story was included as a bonus in Super DanganRonpa 2. Naturally, there are SPOILERS FOR THE ENTIRE GAME below. Seriously. Don't read it if you haven't played/read through the whole game, because it's got a wonderful story and cast, and it would be a shame to go into it with spoilers.

I did not translate this.

Hyejin gets sucked into her own book she has written. There she became the villainess of her book who is destined to die in the hands of her own exclusive butler. Unable to escape her new life, she embraces it and decided to change her fate that she wrote, in hopes she won't get killed by her butler. It doesn't matter if her life becomes tough or messy as long as she's alive, she doesn't mind! . . . . . "Milady do you favour me or his highness more?" "Of course you." "Then me or your brother?" "...You?" "Am I your favourite, milady?" "...." Why is her butler suddenly acting this way? All she did was stop abusing him. PSA: there are some swear words in this book This is my own story! I did not copy from anyone. The characters are my own that I made as well. On Webnovel, Inkitt and Tapas as well.
