Isekai’d as the Hero/Heroine!

Before my reincarnation, I was a former delinquent and a top-class brawler. Despite this, it seems that I have reincarnated as a game’s heroine who has a family of good standing and a gentle appearance.
In order to protect my life while cooperating with the investigation of an incident, I will try my best to fall in love, but...

A girl who grew up as the granddaughter of a gangster family was reincarnated in a otome game, where the early modern mafia makes a secret move. She was the beloved daughter of the five major families that support the monarchy from behind the scenes. A dangerous love game between a former gangster's granddaughter and a villainous fiancé begins.

Sherazade is hit with a flood of memories of a past life, in which her current life is just a Teen Love novel. Her life is about to go from tragic to downright traumatic, and she's not about to sit around and let it happen.
• Part of an otoge isekai series
• Content warning: gang rape (one panel and it’s of the original heroine; explicit parts are cut off by the panel); flashback of sexual assault of a child

• Note: The title is confusing. It seems she becomes the heroine.

One day, she finds herself reborn as Nielce Glory, the main character in a revenge novel and the strongest witch around—a title she earned by single-handedly taking down the Church. Despite being determined to leave all her grudges behind and face the miserable life she's supposed to have, she ends up saving Harvil, the templar who's fated to kill her later on in the novel.

In the R-rated trashy novel "Monster Duke" I married the male lead, Baras, known as a murderer. I am possessed by the female lead, Selen, who lives imprisoned for life. Although he is a respected war hero, I am confused because Baras, who is feared for his cruel 'salvation' when the full moon rises, didn't imprison me or torment me, unlike in the novel.

100 deaths, 100 reincarnations, and sick and tired of life being frozen at seventeen years old.
She decides to murder everyone.
• Content warning: racism; crazy violent and murderous kidnapping and such shenanigans

• Kinda shoddy translation. Either the heroine or the main female character who is the sister of the hero.

I became Kang Seo-yul, the overpowered protagonist from the novel I used to read. A second life that began with full knowledge of the original story’s future. In a world where everyone grows through the system, I am the only one free from its rules.
