Every family has to put forward a woman of suitable age for the prince's selection of a consort. Prince Ji Yi is said to be cruel and unpredictable, and Lin Zhitiao's younger sister refuses to go at any cost, so Lin Zhitiao has no choice but to take part.
One night, a comet streaks across the sky. Lin Zhitiao sleeps especially soundly, and the next day she discovers that her sister has changed.
Her sister seems like a completely different person. Not only does she say she'll enter the selection, she also makes thorough preparations to dazzle everyone on the day.
Lin Zhitiao accidentally overhears her sister talking to a maid, saying things she can't understand, like being reborn, ascending the throne, and wealth and glory.
Since her sister intends to participate, Lin Zhitiao might as well help make her wish come true.
Her sister doesn't disappoint Lin Zhitiao's careful preparations. She is chosen by Ji Yi, enters the prince's residence, and becomes a phoenix overnight.
Not long afterward, Lin Zhitiao meets a refined young gentleman. He's gentle and considerate, and the two pledge themselves to each other.
Then one day, rumors spread that Ji Yi, who has always doted on her sister, has given her to an actor. The entire capital is shocked.
Lin Zhitiao goes to the prince's residence to plead for her sister, only to see the refined young gentleman she's been longing for, building a little stream in the residence where she can enjoy floating wine cups along the winding water.
The refined gentleman, or rather, Prince Ji Yi, comes over with the familiar, gentle smile. "I was only returning your sister to her rightful owner."
In her previous life, her sister met secretly with an actor and became pregnant. To protect her reputation, she got rid of the baby and framed Lin Zhitiao, who was on the verge of becoming empress.
Ji Yi remembers everything Lin Zhitiao's sister did on her behalf.
One-on-one romance, happy ending.
