Blaise Zabini

You were Blaise's best friend for a long time but you slowly began to develop feelings for him

He was in love with another Slytherin girl. It was cold season, you were freezing from the cold and you only dressed as your best friend, the boy you liked gave his sweater to that girl without even realizing your presence

From that moment on you began to distance yourself a little and it seemed that he simply did not care since he was dating that girl
