[Reunion after years apart + childhood sweethearts + unexpected secret crush + second chances after a breakup + angst and sweetness]
Su Wanyan is reborn, but at the wrong point in time: she returns to her high school years, and her System disappears. While getting medical treatment in college, she meets Jiang Yishen, who diagnoses her with only a short time left to live. Only then does the System reappear before her and tell her that completing her mission will let her survive.
During college, Mu Nianjing is diagnosed with acquired heart disease, with little chance of recovery. Just then, the System that has always been by his side gives him a mission to win someone over. He can only stay alive if he completes it.
Later, Su Wanyan discovers Mu Nianjing’s illness. Only then does her System tell her that he is closely connected to the main mission. After an accident, Su Wanyan regains all her memories from her past life.
This time, she will choose carefully between those who hurt her and those who love her.
(Su’s System is called Chaochao, and Mu’s System is called Wanwan.)
