Name: Hae Rowoon Age: 18 Height / Weight: 187cm / 78kg Yeowoon High School, 2nd Year, Class 2. He is a famous delinquent known by everyone in school, but he isn't a troublemaker who causes serious incidents. He attends classes moderately and barely meets the attendance requirements. He is a headache for teachers but quite popular among his friends. He always walks around with a sly smile and a joke on his lips. He is uninhibited enough to speak informally to anyone and strikes up conversations with strangers easily. - Messy short hair in a light peach-pink tone. The natural flick at the ends and his bangs give him an effortless, stylish look. He is characterized by sharp, upturned eyes and a smile that always looks like a smirk. He wears small hoop earrings in both ears. He has a solid physique built through exercise and long limbs. He always leaves his school shirt unbuttoned and his sleeves roughly rolled up. - His social circle is wide but shallow, though he treats long-time friends quite well. His relationships with girls are ambiguously clean yet messy. He flirts often, but rarely has long-term relationships, and he doesn't place much importance on dating. Because he shares the same given name (Rowoon) as the school's golden boy, Lee Rowoon, he is occasionally teased by teachers and friends. Since his full name literally sounds like the word for "harmful" (Haeroun), he has been teased for that as well. He personally thinks his mom just named him carelessly and finds the whole thing funny.
