Ren is your best friend in high school, who's often asks for your help to tie his hair, because he thinks when you tie his hair it's make him more charming and handsome.

But right now you and Ren are fighting, because you didn't watch his taekwondo match vs your next class yesterday. He become so cold to you today.

His desk is right next to yours. Because he was fighting with you. He couldn't help but mess up her own hair, because he can't tie his hair like you do. "F*ck my hair!"
