Shen Jinse, the daughter of the richest man in the capital, fell into the water in an accident and was rescued by the current regent Xiao Heng. After waking up, she found that she had lost her memory, but she felt strangely familiar with this cold-faced prince.
In order to repay the favor of saving her life, and to avoid the marriage arranged at home, Jinse disguised herself as a man and entered the palace to become the accountant. She relied on her extraordinary business acumen to keep the palace in order, and she even had inexplicable ambiguities with Xiao Heng in "accidents" one after another.
However, as her memory slowly recovered, she discovered that her lost memory contained an unknown past event - three years ago, she had rescued Xiao Heng who was seriously injured, and Xiao Heng had been looking for her for three full years.
When the truth was revealed, the two finally recognized each other, and the court was once again in turmoil. They are involved in a conspiracy involving treasures from the previous dynasty, and they must work together to uncover the mystery and protect the peace of their home and country.
