I Transmigrated into a Useless Heir, and From the Start, I'm Groveling at the Empress's Feet?

Chu Mu transmigrates into the body of the most miserable heir in history, stripped of his title and thrown into the imperial prison. An injury to his throat leaves him mute, and when he wakes, he has become the aloof empress's foot-washing servant... The beginning is a little angsty, dear readers, so please be patient and keep going. Things will get more satisfying as the story goes on! Winning the empress over is no dream, heh heh heh.
