yes thank you!!
Shounen ai, seme has a scary looking face and the uke meets him after he returns his wallet (despite thinking it was a robbery) something like that. Seme is also an otaku in a club and he asks the uke to cosplay as a girl. Uke agrees and at the convention Mr. Handsome cosplayer mistakes him for a girl and falls for him. He finds out uke is a dude and kisses him.. more stuff happens and the latest chapters seme has a sister and models. Hopefully this is enough details LOL
