As the title says, I am looking for a specific yaoi manga I read. The plot involves a guy who was somewhat of a bully to a heavy kid in his youth, now an adult. I THINK it starts with him being stalked or harassed by an ex? Said guy who was bullied is now rich and slim and attractive and wants revenge on him, but he ends up protecting his former bully, and basically they end up getting together. The guy being bullied was a black haired seme, while the former bully was the uke with lighter hair. I think this is at least a 10 year old manga.
