You Yiqiao (played by Zheng Shaoqiu) is the undisputed king of billiards. However, one day, he suddenly announced his retirement. However, You Yiqiao's passion for billiards has not diminished at all. His father's decision puzzled his daughter You Jiale (played by Zhou Liqi), who also loves billiards. One day, You Yiqiao met a man named Jin Ziqian (played by Deng Jianhong), and discovered his hidden outstanding talent, so he accepted him as an apprentice, and You Jiale went with the flow and became Jin Ziqian's senior sister. Jin Ziqian secretly admired You Jiale, but You Jiale's heart already belonged to Lei Jianchong (played by Guo Zhenghong). Lei Jianchong is his father's strongest opponent. He is insidious and cunning, and he does whatever it takes to gain benefits. Under Lei Jianchong's instigation, You Yiqiao and Jin Ziqian had a misunderstanding and a conflict broke out. They decided to rely on billiards to decide the outcome.
