Questions! A lot of it.
1. The Emperor (who supposed to be the "husband" of these two) is also a woman?
2. The MC is Gufei (pretty damn high ranking) the other is an effing Empress. The Emperor is just letting themselves getting NTR'd just like that?
Well, interesting premise though I still think gongdou is one of the pointless fight ever (right next to jiadou).
