On the race track at dawn and dusk, the driver tenderly embraces his beloved after winning the championship. His beloved unexpectedly discovers she is pregnant, but is strongly pressured by the elders of the driver's family. On a rainy night, the driver proposes to her on the track, but his beloved, under intense family pressure, leaves in pain and loses the engagement ring. Six years pass, and the two live separately. The driver raises his son alone with the help of a woman, having separated back then to protect his beloved from family harm. After their reunion, they keep encountering each other in various places, with complicated emotional entanglements and tensions, even facing a sudden incident that causes chaos at the scene. Although they sometimes argue and clash, they still care deeply for each other underneath. The child is seriously ill and hospitalized, urgently needing a blood transfusion. The race car driver, despite the risk, insists on donating blood to save the child. Family members trigger conflicts that cause disturbances, and a subsequent Paternity Test resolves years of misunderstandings. In the end, the driver takes out the ring from that time, the two reconcile, and the family of three reunites, reaching their own happy ending.
