help, please!!

um, i'm looking for a yaoi that was a side story!! the storyline:
the seme is a total woman's guy and the uke was a punk. apparently, they've spoken once since they were kids (seme proposed to uke and said they'd marry (?) each other in the future when uke was crying). uke became devoted to seme but since he's a punk/delinquent, he labeled himself as "subordinate". at first, seme found uke troublesome since uke follows seme everywhere and the girls are scared of uke, but seme doesn't really mind because uke's quiet or something. to get rid of uke/make him scared, seme told uke to have sex (?) with him. he thought uke would go away but then uke went to seme's house and they half did it until uke eventually passed out and at the end, seme found him cute.
this side story has a couple of chapters. each different, and their relationship eventually evolving to those of legit lovers and they live together. please help me!! thank you, and have a nice day!!
