Niki's Manga

This is so fu*ing creepy
Story:
A dude works at a company. He lives alone and yet everyday he has a dinner set up just for him. He has a stalker who instaled cameras in his house, he buys him stuff, he cleans his flat - he basically takes care of him but he never showed his face to him. However the stalker became more invasive. He met the dude but he wore a cap and a hood. The dude didn't approach him - he's stressed as hell and din't really do much about the stalker.
In ch- 30 he finally somewhat attacked the stalker (who is living with him since few chapters back. Oh and they have sex/rape). After the sex happens the stalker goes his way thus leaving the stalked one alone. the stalked one is getting more and more frustrated and lifeless at the same time. He calls another dude (who is the stalker's relative or even twin I guess) and requires some help. So they decide to somewhat switch the roles for them - the stalked one turned a little violent and kidnapped the stalker. Now hes holding him tied up on a chair in his apartment. he released him few day after that - cause he couldn't sleep, that guy was moaning. Anyway they actually start to feel for each other I guess??? Then end up together and they probably moved out. It's a little confusing,
