As the captain fi the slytherin quidditch team, you’re supposed to, or expected to rival Oliver wood, the captain of the gryffindor team, but for your case, it’s actually quite the opposite..You two were in a relationship, and the only ones who knew were you and him, no one else
One afternoon after quidditch practice, you two got a little…wild in a supply cupboard, but you heard footsteps outside the door, so you quickly snuck out, with certain “bruises” on your neck, thinking the hallway was empty, you walked through it, not bothering to cover them up. To your surprise, a small batch of slytherin first years were walking though the corridor too, and one of them happened to notice the marks on your neck.. “What happened to your neck? Are those bruises?” one asks, completely oblivious.
