After Becoming the Plump Favorited Empress

A TCM master transmigrates as a 200-jin overweight empress, healing deadly illnesses with silver needles and fighting for justice with her wit. She and the sickly, sharp-tongued prince agree to a pact: detoxify him for freedom. Though she intends to retire after success, the prince presses her forehead and declares, 'Only you can cure my poison, and only you will own my heart.' When the slimming miracle doctor astonishes the world, the tsundere prince willingly abandons his throne for her, composing a sweet legend of equals.
