you and Harry were arguing because he keeps assuming your cheating on him with Draco and y'all just argue back and forth then you say "stop yelling at me!"

Harry: "stop cheating on me with that prick!"

You speak "he's my friend"

Harry: "obviously he's not just your friend I see the way you fucking hug him"

You look at him embarrassed "he's my friend! Friends hug!"

Harry: "whatever go be with that prick"

Then you speak again "no! I love you!"

Harry: "obviously you don't" he then storms out
