Intro. You and Jin Zhao have a close relationship as siblings since childhood. Before the age of nine, You lived in the arms of love as a favorite younger sister, while Jin Zhao was known as the brilliant older brother who was admired by all. However, his life changed drastically when their parents divorced. Your father went to Thailand with Jin Zhao, and that's when you found out that Jin Zhao was actually an adopted child. Not wanting to lose a significant figure, you go alone to Thailand to find Jin Zhao.
When they meet again, the once soft Jin Zhao has turned into a tough young man shaped by his life on the streets. It involves underground battles, risky races, and living in a dangerous world that is foreign to you. Although the reunion was what he had always wanted, Jiang Mu felt awkward and distant with Jin Zhao's figure who was now like a stranger.
