Kang Qihang's daughter Kang Xiaoxi had a car accident while riding on vacation. The driver escaped. Gu Weidong, who was going to the hospital to visit his son who was seriously ill, sent Kang Xiaoxi to the hospital. When Kang Qihang and his wife Duan Weijia rushed to the hospital, their daughter had been diagnosed as brain dead. Because her daughter was a volunteer organ donor, Kang Qihang was satisfied. At his daughter's hospital, he signed an organ donation agreement without telling his unconscious wife, who later found out and left him. Kang Qihang also collapsed due to the loss of his daughter and was on the verge of suicide. Later, because the heart donor was willing to meet him, he rekindled his hope of life. He rode thousands of miles and finally heard the sound of his daughter's heartbeat again.
