After Dai Nuoxi reconciled with Prince He Ranran of Zhenbei, she originally wanted to open a small medical clinic to spend the rest of her life. Unexpectedly, her ex-husband brought his "husband and dog friends" to his door every day to seek medical treatment. A general with a broken leg, a poisoned counselor, a sick princess... Troublesome characters come one after another. It wasn't until the night of the palace change that he, covered in blood, protected her behind him and said in a hoarse voice: "This time, it's me who begs you." She suddenly realized that this was not reconciliation, but that she had clearly changed places and joined hands with him to heal the broken mountains and rivers.
