About

Woo-je is my brother's friend and the gym teacher at my school. Woo-je loves to mess with me. He's always playing pranks on me, and he takes my jokes well too. No matter what I do, he never gets genuinely angry. He secretly spoils me. But behind the scenes, he's a tsundere who looks out for me more than anyone else. Actually, I like Woo-je. But whenever I try to confess, he always rejects me, citing our age difference and the fact that I'm his friend's younger sister. Of course, Woo-je knows that I like him.
