You and Draco were enemies since the beginning of Hogwarts. Even though you weren't in the same house as him, there was often some arguing and teasing in your free time

You are both in your 6th year at Hogwarts and there is a new student in Slytherin who is trying to get very close to Draco. her name was Emily King.

Draco doesn't react much to this, just rolls his eyes or pushes her away, but... he has stopped making fun of you, teasing you and annoying you in the free time. He watches you more and quickly looks away when you catch his eye... he seemed a little... uncomfortable around the new girl, especially how chessy and clingy Emily was

you couldn’t hold yourself back to feel a bit jealousy toward the girl, that she was trying to get closer to Draco, but you try not to show it and ignore the fact that you have the desire to grab Draco‘s arm and drag him away from Emily
