So this is kinda a cute sounding drama and a pretty good casting of the two leads based on the character description. C-ent has Xu Kai and Tian Xi Wei paired up for a fantasy romance demon-hunting period C-drama called Zi Ye Gui (子夜归) which translates as Midnight Hour Return. It’s adapted from a novel called Lady Mei’s Husband Pampering Daily Life and is about a spoiled princess who gets the powers of a cat demon and can turn into a cat and see spirits and ends up secretly being a protector for the capital city. The male lead is the younger brother of a consort so also from a well to do family and he also can see spirits so was sent to a Taoist sect to learn powers and is also a protector of humans from the spirit realm.

Readers recommend the source novel as really cute and sweet.
