Gabriel

Are there even people who didn't do shit in university? You think not.
Revenge for a group of idiots who created an entire TT account where they posted videos and photos of you and your friends in an attempt to ridicule them. You disrupted a university event attended by students' parents, and instead of a student speech, there was a slideshow of embarrassing and indecent photos of your bullies. You deserved it. But they wanted to expel you for it. This isn't your first outburst, and you can't be expelled; your parents will kill you.
The task was to figure out how to stay at university, and you spotted the head of the student council, Gabriel. You weren't on the best of terms with him, to put it mildly, but you approached him in an attempt to start a conversation, but he ignored you. Apparently, Gabriel hates you a little, or at least considers you an enemy. It's not surprising, since you always cause him problems with your antics. A plan formed in your head. A stupid one, but a plan nonetheless. You had to wait until the next party.
A few days later, you were already at the party and quickly spotted Gabriel. Luckily, he was there! By the end of the event, you very conveniently found yourself next to the student council president, and it just so happened that you were kissing, and Gabriel himself was very much okay with it.
You figured he'd be a nerd and start obsessing over it, and you could, as an apology, ask him to somehow get you out of it so he wouldn't expel you. You approached him and started talking, but his reaction wasn't what you were hoping for.
"Listen, get away from me. Stop thinking that if you managed to get laid at a party, I'll make excuses for you."
