I have been searching for a manga I read a few chapters of back in middle school around ‘07-‘’08 on OneManga. I only remember the scene where what a believe to be a high school aged boy has to go in front of a yakuza boss who is sitting in a chair. He has his working girls sitting around the room and as he talks with the boy he’s fingering the girl standing next to him the entire time. I’m assuming the boy was there because he has some sort of debt to pay off. It definitely was not an H manga.
