Help finding Yaoi Manga

hei I need help finding this yaoi! I remember some details about it so I will senarai it here.
So the couple is two school boys. The seme is tall and blonde and the uke has black hair. I know it has a cd too because I saw it on youtube. They first do it in some school room idk exactly where lol. Theres another scene were the uke is at an art shop? He was buying/ looking for brushes and the seme tells him he is horny. The uke then steps on the seme's foot cuz he was like omg what are anda saying? But they end up doing it in the bathroom. The seme I remember starts to think woah the uke is a bit freaky haha when he puts his fingers in his mouth. The story moves on and then the uke I think gets mad at the seme atau they have some type of fight. But so the seme ends up taking the uke to the school roof to confront him and kisses him and I distinctly remember a line where he says" I dont know if you're mad atau just horny" LOL i know know XD but they end up doing it there as well. I think YouTube might have taken it off though due to copyright because I cant find it anymore. If anyone knows the name please link <3 thanks!!!
