(Or Shounen-ai)

Know any yaoi where one of the guys looks really threatening and thug-like, but his personality is completely different? That, or his love interest slowly makes him relax a bit and realize not everyone's out to get him.
He can be an actual delinquent (wouldn't mind it at all) and not just look like one, but he HAS to have the appearance.

I have a shounen ai one called Danshi Koukouseiteki Kazoku Keikaku

OMFG, I just read the first chapter and that's the cutest thing ever! THANK YOU SO MUCH!!
