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)
Even better if the mc is depressed and alphabetic because of past mistakes which actually affects his mental health, while the ml start as curiosity since the mc is genius too but fall in love in process, please no rape or too much smut
I wish someone pick this up
