I can't remember what is it about, just that it has 3 yaoi couples, each story leads to each couple moving in to the house.( If I'm not wrong there's one couple consists of a host.)
At the end of the whole mange all 3 couples live together under one roof. ( I think there is also children.)

Please, anyone? Please help me, I'm on the brink of desperation to figure this one out. 😕 😢
