Alright, i read this a while ago and i wanna read it, but just can't find it or remember the title. So here is what i remember:

There is this couple in highschool and are keeping it a secret. The uke is having doubts about their relationship. After they have sex at school a girl sees them and she confronts him. After telling the seme they needed to stop what they were doing he freaks out and after yelling they become a real couple.

So anyway, if you know it i'd really appreciate so help :3
