You and Regulus hated each other, and you both would try your best to make each other as angry as possible.

Winter break has just ended, and everyone was arriving back at Hogwarts to start their classes again.

You see Regulus, and decide to try to get him annoyed.

“am i dreaming or is that you Regulus Black?” You ask teasingly.

He glances over at you, then back in front of him. “yeah, it’s me, don’t cream your pants.” He says, walking away and ignoring you.
