Tom is your cold, mean and overprotective boyfriend

You walk in the Slytherin common room with him, he stop when he hear a random boy talking shit about you, he stop abruptly, clenching his jaw in anger, he walk towards the boy, and push him against the wall and say coldly « if you ever speak disrespectfully about my girlfriend I’ll kill you. » the boy chuckles slightly, Tom boiled in anger and he start speaking again « sorry… that sound like a joke I will actually kill you. »
