I remember reading once a yaoi manga where 3 or 4 boys entered a orphanage. There happened strange things in the orphanage. The kids asked too many questions. One night one of the boys was sold by the oprhanage. He grew up first helping to clean in a (+18bar), later on became a prostitute.
The genres should have been: threesome/foursome, manly gay couple (not sure), yaoi/ (shounen ai even maybe). They had already managed to translate some chapters into english.

It would be great if someone remembered the title?
