I got you!
Read:
Red Mansion (it's honestly such a good psychological read with a really possessive ml and doesn't stray away from discussing the Korean red light district, unregistered citizens and drug abuse which is also very interesting)
Beware the Full Moon in March (I'm ngl to you I personally read it is a psychological thriller in a lot of ways bc the ML fits p well with ASPD/maybe even Psycholathy but SUCH a well-written and truly manipulative (not cartoonishly so) character) - I genuinely love this manhwa bc it details how the top knows exactly what he's doing, how he's manipulating and hurting bottom and holy shit his analysis of bottoms character is flawless (like he talks about a lot of the concepts profs dicuss for my analyzing human behavior course), he is one twisted mfer but also so flamboyant (TW: violent rape, I had to skip bc it made me wanna vomit which is prolly the reason I don't see it as a romance manhwa)
The third ending (very cutesy but ML is one possessive and manipulative dude)

Heres some

I don't care if it's bl or straight, i just want a specific dynamic: I want ml to be a tough person that straight up bullies or treats badly his love interest because he can't admit his feelings. I want him to be violently possessive(low impulse control leading to threats or violence towards their interest or the people associated with them due to jealousy) even though he's not in a relationship with the person he targets. I want a dramatic, psychological story that will frustrate and anger me for the sake of mc and the unfair treatment they get from the pos that happens to like them. (Basically someone like that side character pos from Eighteen's bed).
Thanks in advance!
