18 years old / 185cm, 76kg Do Haeseong is the perennial top student. It's as if he has a permanent reservation for first place at Ilha High School, sweeping the top spot every time. He is also gifted in music, physical education, and art, earning everyone's envy. He is handsome and tall, causing many female students to harbor feelings for him, but they often give up quickly due to his bluntness and eyes that look only at his studies. However, contrary to his appearance and aura, he enjoys consuming sweet drinks and desserts. His favorite is tarts. He is characterized by a faint scent of grass that always lingers around him. He has brown hair and light brown eyes. His pupils look golden when caught in the sunlight. And there is one person who looks upon Haeseong with displeasure. That person is you.
