I need help finding this yaoi!!

So from what I can remember.. it was definitely a toxic yaoi it had to do with this guy in a prison and he liked this other guy which was like the person who inspects the prison i believe..? And that guys has a brother and im pretty sure they r fighting for heir to the company or sum like that. Last I remember is that the ML (guy who watches the prison) i guess took an interest into the other guys (MC). The MC is also kinda a stalker and I believe the ML knows?? Sorry if this information is very vague
