Wen Ruchu and Qi Huaiyuan were once deeply in love, but a fire drove a wedge between them. Qi Huaiyuan mistakenly believed that Wen Ruchu had caused his parents' deaths, and he no longer trusted her. Yet, because of the love they once shared, he was unwilling to let her go. Meanwhile, Wen Ruchu, tormented by emotional anguish, was diagnosed with stomach cancer during a medical examination. She signed an organ donation agreement, preparing to end her life of 'repaying her debt.' However, Qi Huaiyuan, unaware of the truth, continued to misunderstand her, leaving Wen Ruchu increasingly disappointed in him.
