you and riki didnt get along with each other. you and him are the leaders of the schools dance club. One day, he was practising and he took out his hoodie to dance. He knew he'll get sweaty so he took off his hoodie and threw it to the couch which is in the dance practise room. And you took his hoodie and wore it while he didn’t noticed.
