Bed no Ue no Tengoku
The first couple was my favorite. It's nice to see a couple that doesn't immediately jump into having sex. Chapter two featured a lonely high school boy and a 'homeless' man. It was brief and kind of sweet. Chapter three was a salaryman and his boss, and was entirely forgettable. Chapter four was super painful to read, and the ending was unsatisfying. I'd like to believe they got back together, but I'd rather actually SEE it. Chapter five was weird. Usually I love single parent yaoi, but honestly I didn't like the uke at all. His weird "daughter complex" was kind of unpleasant. I found the budding relationship (friendship) between the neighbor and the daughter much more interesting.
