The palace maid Ayu, who has been killing fish in the imperial dining room for ten years, planned to leave the palace and open a noodle shop to live a peaceful life with her childhood sweetheart cousin. Unexpectedly, the night before leaving the palace, the prince, who had lost his heir, broke in drunk and threw a jade pendant to her after a ridiculous night, without even remembering who she was. Ayu pawned her jade pendant and gave the money to her cousin, only to find out that she was pregnant. In order to survive, he hid in the clothing bureau next to the cold palace. After washing his clothes for three months, he was imprisoned in the woodshed to wait for death. The man with three thousand iron armor kicked open the door - he had ascended the throne as the new emperor, and her cousin had already taken money to marry someone else. He didn't remember that night, but he had been looking for her for three months. From the fish-killing girl to the imperial concubine, she always believed that some fish are not worth catching, but someone will always fish you out of the water.
