In his past life, Zachary realized on his deathbed that his wife and daughter never loved him. Reborn seven years into his marriage, he decides to let them go and devotes himself to medical research. After a painful divorce, he moves to Jing City to study brain cancer, where he meets young patient Coco and her aunt, Xena. With Xena's support, Zachary pursues research abroad. Ten years later, he returns as a successful scientist. At his apartment, both Xena and his ex-wife await him—each holding flowers, each with hope.
