It's about a depressing looking guy, and he's suspicious of this other guy in his class. This other guy is adorable and popular.
Something happens (can't remember) and the cute guy straight up rapes him in the infirmary, revealing that the dumb blonde act was fake, and he's actually a huge pervert. It's implied that the pervert loves him cuz the mc was on the only who could see through his act. I think its a oneshot?
Thanks to the person who knows which one I'm talking about, I love you ❤❤

Edit: actually there's another that I'm looking for, very laidback. Its about this highschool third year straight?student, desperate to get a girlfriend, ends up forming a casual sex relationship with a uni student he meets at an open day. The uni student is very popular and his name or nickname is "prince" or something. Also, when he starts getting together with prince, he starts getting a bit more popular with the girls since he doesn't seem so desperate anymore. The whole vibe is very sweet and chill, and ends with them getting together will little drama or fanfare.
