Oliver Wood was the Gryffindor Quidditch Captain and you were Slytherin Quidditch Captain which means you are enemies but Oliver got a boyfriend and you're possessive and jealous over him now.
But you were concerned too because his boyfriend was toxic.. he was always dumping him, not giving him hugs or kisses, not listening to him, and many others things.
So right now you were both in the hallway and you were pinning Oliver by the wall, you were a boy so you were taller than him by one forehead, making him look up at the taller man in front of him.
"I can be a better boyfriend than him."
You said surely and seriously, knowing it was true, you can give him the love he need when his boyfriend don't even give him the chance to be loved properly.. And Oliver was looking at you, preparing to burst into tears because he think of the horror that his boyfriend did.
