The Oriole Behind You (смешанная)

Instead flaunting his power by forcing twenty juniors from each clan to be taught by his incompetent son, Wen Ruohan decides to take a subtler route. At Qishan’s Grand Discussion Conference, every clan heir and their second-most prominent disciple finds themselves forced into a marriage carefully crafted to mock them.
Worst affected is the Gusu Lan Clan, where the Twin Jades find themselves in marriages to two men. Lan Wangji is ordered to marry the shameless Wei Wuxian who touched his forehead ribbon, and Lan Xichen is ordered to marry the widely-mocked bastard of Jin Guangshan... who may be less innocent than he appears.
