There was no way the old contract Jiang Cheng found arranging a marriage between the direct disciples of the Nie and Jiang sects was, as Jiang Cheng insisted, the way to solve the problem of the Yiling Patriarch - if only because there was no way the Nie sect would agree to it. Except - they did. And now they're coming to discuss terms. With Lan Wangji as the official chaperone.

When Jiang Yanli joins Jiang Cheng in visiting Wei Wuxian at the Burial Grounds, the two brothers are on the verge of cutting ties forever — until Jiang Yanli has a better idea. Wei Wuxian doesn't need to leave the sect. He needs to get married, and she has the perfect Sect Leader in mind. When Lan Wangji is invited to come along on Wei Wuxian's visit to the Unclean Realm to spend time with his new betrothed, Nie Mingjue, he agrees — even though his heart is breaking. How else is he ever going to see Wei Wuxian again? When Nie Mingjue welcomes Wei Wuxian and Lan Wangji into his home, he realizes two things very quickly: 1.) They clearly want each other so badly they can barely stand it, and 2.) Nie Mingjue is Into That. (In which arranged marriage to Nie Mingjue solves just about everyone's problems)

There has always been a divide between the sect and the clan. The clan flows through the male line, heritage and paternity, but it is the wife who comes from outside that rules the sect - a measure, Lan Xichen thought, put in place to prevent war between the sects. Who would want to risk antagonizing someone who might end up running your sect some day? And then Nie Mingjue's father died.
