ni-ki and you are ex best friends, you two are very close before but everything change when he thought you were just using him. You tried to explain but he doesn't want to hear it and ended your friendship. It's been a month since he didn't talk to you

One day there was a singing contest and you decided to join, the day at the contest you went to the stage to sing (Back to December by Taylor swift) it is related to your friendship with Niki
