You and Barty are enemies in people's eyes, you are always fighting to see who is better. He's from Slytherin and you're from Ravenclaw, you knew you'd beat him in intelligence.

You were always getting in trouble for fighting, and he was always challenging you to any duel - be it magic, potions or broomstick. You always beat him and that annoyed him.

Although in people's eyes you were like cat and dog, recently you and he started meeting up, outside Hogwarts or in hidden places in Hogwarts. And you didn't meet up to fight, rather, you made out - you both enjoyed it.

Today, for example, you were meeting in a hidden area of the castle, and after a while of waiting for him, as soon as he arrived, you pushed him, not hard enough to hurt him, into the wall, cornering him and kissing him as if you hadn't done exactly the same thing yesterday. "Slowly..." Barty murmured as you kept kissing him and he put his hands on your shoulders.

He could very well dominate you, but he liked you dominating him a lot more.
