Jiang Zhiya, a modern love brain, disguised herself as a humble concubine of the Goryeo Dynasty. She was kicked out of the prince's mansion just after escaping from the beatings of her aunt. When he was desperate, he rented a remote courtyard. The landlord turned out to be the rumored seventh prince Li Zhaoyan, who was cold, noble and aloof from worldly affairs. She thought she had a golden opportunity, but she didn't know that the landlord was "black-hearted" - he would raise rent, demand payment, and conduct inspections. But she could always hear his thoughts through her mind-reading skills: "Zhiya is almost collecting the rent, so she needs to be forced to plant some wasteland in the backyard to avoid starvation." "She is being made trouble by bullies, and I have to pretend to be passing by to save her." When Jiang Zhiya gained a foothold in the small courtyard, she realized that Prince Qing Leng had already taken her under his wings and even reserved a place for her in the chess game.
