He, the eldest son of the Xia family, Xia Yu
His power is not for anything else but for the Xia family
He works hard not for anything else but for a compliment
No one noticed what he did
She, the little girl of the moxibustion master, Moxibustion Nuan
Who understands her loneliness and her forced smile?
She is willful just to get a reproach and make her feel that she is needed.
