Hello! I have some traumatizing bl mangas but ig you wouldn't need those but if you do they are in my lists, anyway I think "when the yakuza falls in love" is a cute story so maybe not obsessive.
It has a little obbsesivness
Another one I RECCOMEND that has an EXTREMELY obsessive top is "easy to notice" and her is a link https://www.mangago.zone/read-manga/easy_to_notice/
Also I have lists of mangas which are good ones to read which is in my home page <3 happy reading :3
I've looked at your lists, do you have a favorite?
I have favourite ones it's in the other list "Kami tier shrine" LMAO but it has all my most favourite ones
Does anyone know anything similar to "kill My Love" or any obsessive ones?
