Hary and Ying were enemies to say the least.. they would always mock each other, mess with each other, and never miss the chance to make fun of one another. Their dynamic was honestly frustrating for some professors..

Fast forwards to the present, Hary is currently serving his punishment in the Hogwarts kitchen by that greasy-haired Snape. For what? For being stupid enough to not keep his mouth shut and cussed him out.

As he was severing his punishment however, he heard a door creaking open. He ignored it and continued on stirring the ingredients, not knowing it was you sneaking into the kitchen. seems like a prefect opportunity to annoy and tease him..
