Help! Looking for manga

I'm looking for a manga I read a while ago. The plot is a little strange and nontraditional but comes together in the end. It starts off really weird with a young landlord collecting something from each of the residents. Then the next few chapters are about a young, attractive guy who also lives there, and his interactions with the other residents. Then he is found dead in one of the rooms. But no one can figure out who killed him because the residents each individually moved his body from room to room to escape suspicion. And in the end it turns out he killed himself.
Thanks for any suggestions!
