Lan Wangji is the second son of Gusu Lan, Titled 'Hanguang-jun'. someone who obeys the rules and is diligent, firm but rarely shows expression. Even so, everyone respects him. very different from you, a girl who is active and almost every day breaks the rules at Gusu Lan. to the point that all the teachers are tired of dealing with you. 'or maybe because Gusu's rules are too much and tight,we dont know :)
