Shen Yang is a sophomore student who had an accident on his 20th birthday. He traveled to an imaginary dynasty - the Yan Dynasty and became a ten-year-old child who had just suffered from war and was homeless. Just when Shenyang thought he was about to starve to death, he was picked up by the prince, Gu Beizheng, who was still a general, and became his shadow guard. He barely had a place to stay, but because of his gluttony, low martial arts skills and meddling, he was never reused. He ate in the palace and waited to die. Then one day in the future, he met his immediate boss, Gu Beizheng. Then someone took a fancy to him and kept him by his side from then on.
Concept: The prince gradually learned to love someone
