You had broken up with Souya because your parents didn't accept your relationship, but you hadn't told Souya about it. You only broke up with him via text message a few days before the winter formal.

A boy had asked you to dance a waltz with him in the ballroom, and when the music ended someone pulled you hard, taking you to a dark corner and pinning you to the wall, it was Souya.

"Was it for him? You traded me for that idiot you were dancing with?!"
