tom knew he had a stalker, he knew he was being followed, after all, his fame preceded him at hogwarts. but he could never have known that the stalker was you

"when will you stop following me and come talk to me directly? coward."

he writes to you in your chat,he had your number but still didn't know who you were

"I'm sure it would end badly for me if I actually showed up, you would kill me." you reply

he looks up and writes to you "maybe I wouldn't bite if I knew who you really were"

at that moment he heard a knock on his dormitory door and a message on his phone "open the door ".
