ｎｏｔｉｃｅ ｍｅ ｓｅｎｐａｉ

So j posted this already but it seems nobody noticed me :,( I need answers goddammit

Do you know any manhwa/manga/manhua where a male mc pretends to be nice but actually evil, bad and could kill someone (maybe already killed someone) but pretends to be like he’s happy go lucky but when you turn your back at him he's back to his true evil self.

I’ve already read:
Killing stalking
Dead tube
Prison lab
Kakegurui
Real account


I really appreciate it if the mc’s male and doesnt have any romance on it

Thank youuuu
