MEGA FUCKED UP STALKHOME SYNDROME MANGA

I read this one manga about this dude who got kidnapped by this guy who lived in a small house with bird cages hung up and pictures or something on the walls, the victim was like "how long you gonna keep me here?" and the kidnapper said "27 years" which was really specific and turns out the kidnapper was a victim to a child predator who locked him up for 27 years after the victim dude suggested it to the child predator to take the other dude when they were kids. They both developed stalkhome syndrome from the kidnappings and I think they end up together?? Idk but I wanna read it again!!
