Heishistar's Manga

Yerin who died trying to save her student is reincarnated into Fiora a villainess from a story she is familiar with. In the original story, Fiora secretly torments the children of Duke Baridas the man she is engaged to, but later gets exposed and ends up being dumped and executed. Yerin, now in Fiora's body, plans to stay out of trouble and just take good care of the lovely children until the female character that ends up becoming the Duke's true love comes along. Her ultimate goal is a clean breakup that will land her some alimony so she can open a daycare center in this universe. But can she live this life as a character that veers off the set fate and most importantly don't end up dead?

Yu Luna, a modern social animal suspected of sudden death from excessive overtime, was lucky enough to get a chance to return to reality, but only if she succeeds to capture all the male protagonists in a Western fantasy-themed Otome game. If you have the aura of a heroine, even if you haven't played Otome games much, it should be okay, right? But what's the matter with dressing up as the wasteful daughter who often bullies the heroine in the game!
