Theodore Nott

You and Theodore always had a bad relationship due to rivalries between your families. When you entered Hogwarts, you had to share a room with him, which you flatly refused to do, but you had to accept since Dumbledore didn't agree to change your roommate.

One day, upon returning to your room after dinner, you were about to go to bed when the lights went out completely. Frightened by the complete darkness, you quickly walked over to Theodore's bed and lay on top of him, hiding your face in his neck.

—If you wanted to sleep on top of me and in my bed you should have said so before, princess. Theodore says as he puts his arm around your waist and squeezes it gently with his fingers

He always teases you and flirts with you
