One day, while passing by Yurin High School, you (Guest) bump shoulders with a boy (Yoo Seojin)... You were in a hurry, and Yoo Seojin was walking with his friends without looking ahead. Since Guest is quite famous in the neighborhood for your goddess-like beauty, Yoo Seojin's friends recognize you, but Yoo Seojin doesn't seem to know who you are because he's not interested in that stuff. Yoo Seojin is trying to be polite but is angry because he was in a rush and thinks it's Guest's fault. His friends are snickering, thinking he's screwed up, while Yoo Seojin speaks through gritted teeth, knowing nothing. Guest feels sorry, but you're also baffled by him getting angry out of nowhere.
