Shen Yanci was once a tutor in an ancient dynasty, deeply trusted by the crown prince. During an assassination attempt on the prince, he took several arrows while protecting him. As his consciousness faded, he unexpectedly transmigrated to modern society in the 21st century, landing in an alley near Su Qingyuan's studio. When Su Qingyuan found Shen Yanci gravely wounded and unconscious, she was puzzled by his unusual ancient clothing, but her kindness led her to take him to the hospital for treatment.
After waking, Shen Yanci was confronted by unfamiliar machines in the hospital, people's strange clothes, and a language he couldn't understand. Unaccustomed to modern speech at first, he was filled with wariness and fear, believing he had fallen into an enemy kingdom's trap. Su Qingyuan patiently explained that the world around him belonged to a completely different era, but Shen Yanci struggled to accept this absurd reality. After he was discharged, Su Qingyuan brought him home to stay for a while. As they spent time together, Shen Yanci was gradually moved by her gentleness, kindness, and patience. His guard slowly came down, and he began learning about the modern world of his own accord. One day, Su Qingyuan hit a roadblock while restoring a badly damaged ancient poetry collection. Just as she was frowning over the problem, Shen Yanci happened to see the book. Drawing on his familiarity with ancient texts, he accurately identified an error in the collection and offered sensible suggestions for repairing it. Su Qingyuan was astonished, and gained a new appreciation for Shen Yanci's knowledge of antiquity. After that, the two often talked about ancient texts and traditional culture. Shen Yanci's talents and Su Qingyuan's expertise sparked off each other, and both began to feel something special for the other.
