Does anyone know that yaoi manga, shoujo art style and nice fashions, it's not new genre it's kinda old. The mc dated a feminine guy with shoulder length pink hair, but then the mc cheated and the boyfriend dated another guy, I think he was a mafia Or something. And after that the mc worked for the gang like running errands and cooking for them, the gangsters really liked his cooking. And after some time, the boss (pink hair boyfriend) got interested in the mc and did it with him while still being with pink hair. But then after that they broke up and mc and the boss stayed together. Also mc and the boss knew each other when they were a kid, the mc was known as the handsome kid in school but as soon as the boss entered the school every eye were directed at him. And mc accidentally touched the bosses crotch. The boss also have a very interesting yet common relationship with an old man who is of higher position. The boss got his position because of the old men and I think he was groomed as a child by the old man too, and up to what I read their relationship was still going on like that.
Mc have blonde hair and the boss have brownish black or something.
