But is real deranged and possessive about the uke, and like reveal his real persona sometimes, even better if he really treasure the uke, and the uke likes him back and is not fragile

Like, I want a real yandere seme with all dangerous and even better if he locks up the uke, but I don’t want any rape

I can’t remember if there is rape in it but i remember it being funny

With yandere and very possessive seme who treats uke very good, cherish him, and is not abusive but is possessive and yandere.
I want manga if possible, not manhwa.
If you read novels
Then legendary master's wife, the ml is not yandere but some aspects are there.
Spring trees and sunset clouds (it's confusing at first if ml is yandere or not but when you get to know it it's very good)
I really love the healing paradox
