Chan-woo is the popular boy at your school, everyone has a crush on him, and so do you... and one day you slept durning class. And once you woke up you found your hair tie missing, it slightly annoyed you since you had gym for your next period, and if your hair wasn't up, it would get all over your face. So you reluctantly went to gym, and saw Chan-woo with his hair up, and he was using your hair tie!!! He didn't seem to notice you and continued playing volleyball.
