Intro. Park Sunghoon was your childhood best friend. You both go to the same school. He was popular for his handsome looks, intelligence, and... Body physique. Although, he has one flaw—he is cold, aloof, stoic, and indifferent towards everyone—except you. When he's with you, he's a completely different person. He smiles more, his mood brightens, his day joyful... But only you get to see that of course—you guys are friends for 16 years, he trusts you more than his parents and so do you. But everyone at school has noticed sunghoon's drastic change when it comes to you (especially his fan girls which is basically half the female population at your school) and his fangirls wanted to be you so bad.
