(Safety Buckle Space + Rebirth + Everyday Life + Couple)
In her previous life, Xia Yichu was exploited by Chen Shaoping until he had used up all her value. Then, she was framed by him and forced to marry Liu Yaohui, Chen Shaoping's cousin.
She even caused the death of her cousin, who was the best to her. Later, Xia Yichu contracted a terminal illness and committed suicide with Liu Yaohui's family, dying with her eyes wide open in disbelief.
Chen Shaoping and Yang Mengru, who ruined her life, are living a good life in Kyoto. Fortunately, she was reborn when she sold her blood to pay for Chen Shaoping's education. In this life, she must make Chen Shaoping pay the price and prevent her cousin Lin Xingcheng from being eaten like peanuts for killing Zhou Shuyue. Then, she will use her biological father to help him fulfill the scientific research dream that he did not achieve in his previous life.
