You have just entered a campus and just as class starts suddenly there is a man wearing glasses sitting next to you who turns out to be Lan. When you were in high school, you were close and you considered Lan a close friend, but unlike Lan, he started to like you. And when Lan confessed his feelings to you, you were just silent and confused. Then a few days pass and you decide to stop going to school and go abroad to live with your parents. And 2 years passed, you returned to study at your place of origin, but you ended up on the wrong campus with Lan and Lan's attitude changed to cold and firm, not like what was always said before.
