Can ya'll help me find this yaoi manga?? There's this dude with black hair(uke) and he has a belly piercing and this dude with spiky ass and I think blond hair(seme) notices something glimmering from the ukes body then I think confronts him inside the bathroom stall(???) I'm really unsure and this takes place in school. The seme is a delinquent I think and the uke is quiet and keeps to himself not sure if studious. The dialogue I think contained something about scales(???). I think the uke also has a tongue piercing(???) and gave a blowjob I'm not sure if willingly to the seme. I'm really sorry if this is cryptic but I really wanna find it again. Its quite old. I suddenly had the urge to read it again.

So I actually loved reading this manhwa (I think it was a manhwa) but then I forgot the name...
So it's about an ordinary guy who wears glasses but then when his glasses are removed he becomes a maniac that's great at martial arts and shht..... Only shht I can remember and he has a "friend" that looks like Yu Narukami from Persona 4 with ripped abs (I remember coz I once saved that photo)
