Summary: Right after winning a war, General Wei WuXian has a rude awakening as an omega and is dragged to the imperial palace. While he gets used to his new place in society, he begins to reconnect with his family and old friends--one of which is an ice-cold Emperor who is as hard to read as ever.

Note: This is written in Alpha-Beta-Omega dynamics but not really about werewolves. Lan Wangji is the alpha emperor and Wei Wuxian is the omega general and they are in love with each other. Everyone knows except WangXian. The plot is very engaging and we have appearance of almost every character from MDZS including Wen Xu, Wen Chao and Mo Xuanyu. Still an ongoing story but I always keep checking for updates since it is that good. This one is a must read.
