Carla was your bestfriend til she got accepted to a new school. A wizarding school.

You got accepted as well, and you two are both in the same house. You got a room shared with only her.

It's your fifth year at Hogwarts and Carla was oddly...flirty with you. You wonder why.

When you walked into your room, Carla pinned you to the door as it closed. She kissed you as you were about to say something.
