Great Tang: I Teach at the Imperial Academy

What would it feel like to be an ordinary commoner and suddenly discover that your wife is the emperor's daughter?

Shock? Delight? Or complete bewilderment?

Gu An says he doesn't feel much of anything.

But, Father-in-law, what are you doing?

P.S. This novel has only one female lead. If that's not your thing, don't read it.
