Episode 7 recap: Cheng Biyuan was serving Prince Qi for his bath.

In the evening, they unexpectedly encountered Mu Yuan, Prince Qi's good friend and imperial physician, who had returned from a six-month journey. To their surprise, they found Prince Qi in such a pitiful state, covered in injuries. After hearing Mu Yuan's terrifying account, Cheng Biyuan became anxious and couldn't help but ask him quietly if Prince Qi would die. Prince Qi, upon hearing this, scolded Cheng Biyuan angrily, asking if she could at least wish him well. Mu Yuan reassured her that the external injuries inflicted on Prince Qi were not a major concern, but the internal effects of the cold wind had caused significant damage to his body.

Therefore, Mu Yuan asked Cheng Biyuan to help Prince Qi soak in a medicinal bath at night to expel the cold and dampness from his body. Cheng Biyuan strongly resisted the idea, and even Prince Qi said that it was enough for him to be served by scallions and garlic. However, Mu Yuan explained that he had sent them out to buy medicine, leaving only Cheng Biyuan behind. He told her that Prince Qi contracted the illness to save her, and as a cook who had slaughtered numerous live fish and poultry, she should understand. After this moral manipulation, Cheng Biyuan reluctantly agreed, mentally preparing herself to treat Prince Qi as a big fish.

That night, Cheng Biyuan brought various bottles and jars for Prince Qi's bath. Seeing him closing his eyes in the bathtub, she thought he was asleep and quickly began her work. Initially, she planned to do a hasty and perfunctory job, but when she noticed Prince Qi's injured hand, she recalled how he had protected himself with his bare hands during the Mid-Autumn Festival banquet. Deeply moved, she carefully and attentively wiped his wounds. Unexpectedly, Prince Qi was not asleep, and Cheng Biyuan was startled when she heard him speak. She slipped and ended up leaning on Prince Qi.

Taking advantage of the situation, Prince Qi asked her if she was willing to stay in the palace forever. Cheng Biyuan, in a state of panic and confusion, didn't know how to respond and hastily fled.
