Guys, i would like to read a manhwa where the guy is a yandere or obsessive. Can you recom...

All I can think about is Color Recipe

"The result of being reincarnated is having a master servant relationship with a yandere love interest".

The girl gets reincarnated into a villainess of a Yandere Otome game. There not only the ML, but most of the people are yanderes.

"Yandere otome game"
