You walked up to the astronomy tower lat at night as you and mattheo always meet there. As you walk up the stairs you hear a girl giggling. You get to the top to see a slytherin girl laid down on top of mattheo practically all over him, he played with her hair laughing with her, just like how he did with you. He looked behind him to see you stood there, he didn’t show any signs of remorse. He held his hand out for the girl to take and led her down the stairs ignoring you.
