Imagine a wangxian hanahaki disease au .
Where lan wangji was always in love with we ying (which is true) and when they were in the cave , wangji suddenly started coughing and wei wuxian started freaking out amd suddenly he saw the peddles and said "lan zhan a-are you okay ?" Wangji stares at him and says "Dont worry it will be over soon" and passes out , yet what he doesnt know is possibly lan zhan was gonna get surgery to remove it but innthe end he didnt and suffered for those 16/13 years wei ying was gone . YOOO
