Su Wan, a modern medical student, accidentally traveled through time and became Su Nianxi, who was born with the auspicious "rainfall from the sky". He wanted to pretend to be a dandy to avoid trouble, but the emperor issued an imperial edict and granted marriage to Prince Jing Xiao Jinyuan, who had been in bed for three years and was poisoned by bone rot.
On the surface, she is a well-known "Dandy County Princess" in Beijing, but in fact, she has a lot of modern medicine and medical skills hidden in her. Married into the deserted Prince Jing's palace, while using expired antibiotics and anesthetics to treat Xiao Jinyuan's injuries, she also dealt with the series of schemes between the Queen Mother and the Liu family - poisonous supplements, fake concubines, and kidnapping of family members, every step of which was thrilling.
The sickly prince Xiao Jinyuan was cold on the outside and hot on the inside. From the initial wariness, he was gradually moved by her medical skills and sincerity, and turned into a madman to protect his wife. The two worked together to find evidence of the poisoning, exposed the conspiracy at the palace banquet, and finally put the Queen Mother under house arrest and the Liu family to bring justice.
From healing in the palace to appreciating the maple leaves in Yunqi Mountain, from eating candied haws in the market to coping with crises together, they get close to each other amidst intrigue and warmth. When Xiao Jinyuan threw away his crutch and took Su Nianxi's hand to promise a grand wedding, this marriage that started out as a happy marriage ended up being the warmest redemption in each other's lives, full of sweetness and healing.
