At two o'clock in the morning, in the dormitory of the University of South China, Lin Wanxing, a female student from the Department of Literature, had a heart attack because of the tragic experience of the male protagonist Xiao Che in the ancient Chinese novel "The Proton Story of Dajing" - he was turned into a proton at the age of twelve, was given a drug to develop a cough, and was tortured by the prince at the spring banquet and broke his knees. She couldn't help but leave a message, "I would like to wear a book and cook him a bowl of rock sugar pear water." However, she became dizzy and lost consciousness the moment her phone was turned off. When she woke up again, she was actually dressed as "Awu", the cannon fodder maid of the Clothing Bureau who could not survive for three chapters in the book. As soon as she opened her eyes, she was threatened by the nanny in charge of the stick because "she" knocked over the noble girl's brocade skirt.
Relying on the memory and quick wit of the original work, Lin Wanxing discovered that the crack and leakage in the wooden basin was the reason for the slip. He barely escaped death, but he knew that the Huanyi Bureau was by no means a place to stay for a long time. Looking at the piles of dirty clothes and the biting cold air, she thought of the proton Xiao Che who was also in a desperate situation - he was being imprisoned in the cold garden of the palace, being humiliated and suffering from coughs every day. In order to survive, and to fulfill the message of "help him get rid of the bully", Lin Wanxing decided to take the risk and go to Lengyuan to find the only person in the book who cared about her.
At this moment, in the cold garden, Xiao Che, a young man in plain clothes, was leaning against the window and coughing. His pale face reflected the faint skylight. He had no idea that a girl from modern times with the idea of "saving him" had broken through time and space and was heading in his direction, embarking on a path of survival that would rewrite the tragedy. Will their encounter save each other, or will they be drawn into a deeper palace whirlpool?
