Cai Yanfang is an energetic and self-centered girl, and she tends to offend people because of her straightforwardness. She has a pair of good friends who are twin sisters, Rainie and Liu Xuan. The three of them dream of becoming excellent volleyball players and representing Singapore in the Olympics. Yanfang is the star player of the team and often the focus on the court. Combined with her self-centered personality and her love for self-expression on the court, as well as her habit of criticizing and correcting her teammates, this makes the other teammates both jealous and dissatisfied with her. In an accidental incident, Liu Xuan unfortunately passes away, leaving Rainie as her only friend in the team that she can really talk to.
