Forgot this manga

This is a yandere manga, it’s a bl and well okay the main protagonist looks taller than the ‘yandere, possessive guy’ it’s kind of like a sense x uke reversed, the yandere possessive guy has cameras in his house because his mother has a possessive yandere kind of trait as well, I probably gave vague information but the main protagonist talks about seeing uh a girl naked? I’m not sure exactly lmao and the possessive guy asks who and becomes ‘scary’ and okay well the main protagonist says from a porno, I don’t really remember how the manga goes but on YouTube there’s like voices for this manga and I think the main protagonist is pretty innocent and has no clue about the possessive guy’s yandere’s tendencies until later in the manga, I’ve read this manga once but I want to re-read
