Han Yimo, a 30-year-old diplomat, finally spent the holidays at home, but when he opened his eyes, he was transported back to the time he was in junior high school when he was 13 years old. After reviving her life, she is determined to make up for her regrets: she will stay away from business marriages, and she plans to boldly pursue her childhood sweetheart, Leng Yuxi, and take a completely different life path.
However, what she didn't know was that the young man Leng Yuxi, who still seemed young and immature, had been waiting for her for ten years with memories of two lifetimes. In the first life, he let her go and watched her get married and die alone; in the second life, he died young to save her. In this life, he has been the founder of the "Indifference Group" that has been secretly laid out for seven years, and he vows to protect her.
When Ye Ye, a playboy from the south, pursued her for three years, Hua Ling, a noble prince from the north, silently guarded her, Zhuang Qi, the avenger who returned from overseas, targeted her at every turn, and the Mei family, an international consortium, was eyeing her - Han Yimo gradually discovered that his "simple rebirth" was actually involved in a century-old entanglement between the four wealthy families and the secret war of transnational capital.
What makes her even more uneasy is that Leng Yuxi always seems to be able to predict everything: appearing suddenly when she is in danger, guiding her accurately when she is confused, and even knowing what she wants to say before she speaks.
"Who are you?" She finally couldn't help but ask.
Leng Yuxi gently held her hand, with deep affection and exhaustion spanning a century in his eyes:
"Momo, this may be your first rebirth, but it is my third life. I will never lose this game again."
A guardianship spanning three generations, a puzzle about time, memory and choice, is slowly unfolding...
