In the previous life, the heroine Gu Nian'an and her beloved Lu Shichuan both died due to a series of conspiracy. She was reborn with hatred and returned to before all the tragedies happened. But she soon discovered that this rebirth came with a cruel rule: she could use information from her past life to save relatives and friends who should have died in the conspiracy, but every time she successfully rescued someone, one of the most precious memories of Lu Shichuan in her mind would be erased.
At the beginning of the story, Gu Nian'an resolutely chose "trade" in order to protect his family. She prevented her father's investment from failing at the cost of forgetting her first encounter with Lu Shichuan; she revealed the true face of her best friend's boyfriend at the cost of forgetting their first date. Lu Shichuan was the only one with a complete memory. He watched the girl who once loved him deeply, her eyes changing from fiery to strange, polite and even wary. He must make Gu Nian'an fall in love with this "strange" self again before she completely forgets him.
The cycle is based on the "rescue-forget-repurchase" model. Every rescue is a thrill, and the subsequent forgetfulness is the ultimate test of the relationship between the male and female protagonists. From the initial pain and incomprehension of the male protagonist to the firm protection later, he used actions to fill the memory gaps of the female protagonist again and again, creating new bonds. In the end, when the heroine is about to completely forget him in order to save the last person, the relationship between the two will usher in the ultimate sublimation.
