Sun Yue, the eldest daughter of the Zhenguo General's Mansion, is a little devil who is doted on by the whole family. Because her parents "drew trouble to the east" before the war, she was given a marriage to Xiahou Dan, the prince of the East Palace. This one-of-six lottery marriage was something that the princes would avoid, but it became the beginning of her ten-year relationship with Xiahou Dan. There are undercurrents of intrigue in the palace. Xiahou Dan was guarded by the emperor and the empress because of his life experience. The charcoal tax scandal caused the East Palace to be banned, and the battle for the right to inherit the throne intensified. Changsun Yue accompanies him with sincerity, from ignorance and slapstick to fighting the crisis together. Xiahou Dan had a secret plan, but in order to protect the country and his beauty, he pretended to die and gave up the throne. Finally, he and his eldest son Yue retired to the mountains and forests, away from the palace disputes, and stayed together for the rest of their lives.
