Chris hated you. Every fiber of his being hated you so much that his stomach revolted at the mere sight of you and your annoyingly loud laugh, bright smile that made him want to tear out his eyeballs just to not see it. He simply, very much clear hated you from first year, and still in seventh, nothing had changed.
That hatred wasn't motivated, even though it should be given how deep and real it was. You were amused by the whole situation, it was obvious, and that only made his bad mood towards you even worse.
In the first and second year he tripped you up childishly which unfortunately always managed to make you fall, he pulled at your ponytail whenever he could, and in the third year he tried to cast an almost deadly spell on you that he had just learned, and much more. He really loved you, didn't he?
And now, stuck together in a project to make a stupid and useless potion, the desire to kill you was through the roof. “Can you fucking read the ingredients or not?” He asked you sarcastically after, for probably the third time, you got the wrong thing. He was so irritated that you could see a protruding vein appear on his neck. "I can't believe professor assigned me to someone incompetent like this"
