Shen Yanci was originally a tutor who was deeply trusted by the prince in the ancient dynasty. During an assassination incident against the prince, in order to protect the prince, he was hit by several arrows. When he was unconscious, he accidentally traveled to the modern society of the 21st century and fell into an alley near Su Qingyuan's studio. After Su Qingyuan found Shen Yanci who was seriously injured and unconscious, although he was confused by his strange costume, he still sent him to the hospital for treatment out of kindness.
After waking up, Shen Yanci faced the unfamiliar instruments in the hospital, the weird clothes of the people, and the language he couldn't understand (his initial inability to adapt to modern spoken language). He was full of vigilance and fear, thinking that he had fallen into the enemy's trap. Su Qingyuan patiently explained, trying to make him understand that the times he lived in were completely different, but Shen Yanci found it difficult to accept this absurd reality. After being discharged from the hospital, Su Qingyuan took Shen Yanci back to his home for a temporary stay. In the process of getting along, Shen Yanci was gradually moved by Su Qingyuan's gentleness, kindness and patience. He slowly let go of his guard and began to take the initiative to learn modern knowledge. Once, Su Qingyuan encountered a bottleneck when repairing a badly damaged collection of ancient poems. Just when she was frowning, Shen Yanci accidentally saw the collection of poems. With his familiarity with ancient documents, he accurately pointed out an error in the collection of poems and put forward reasonable suggestions for restoration. Su Qingyuan was shocked and also made her admire Shen Yanci's ancient knowledge. Since then, the two often communicated around ancient books and traditional culture. Shen Yanci's talent and Su Qingyuan's expertise collided with each other, sparks flew, and each had a different affection for the other.
