In a quiet school setting, the swimming club is preparing for its final competition of the year. Most of the main members have gone on a training camp, leaving behind only a few, including Kazuya, who can only do freestyle, and Kawaya, who had to withdraw from the competition due to an injury during practice. At the center of it all is Sakura-senpai, the club president, who, despite being a bit of a motion-averse person, continues to swim because of her childhood asthma. Her dedication and sincerity earned her the position of president, and she remains a strong presence even as the team faces its final challenge.
Kazuya, who joined the club after falling for Sakura-senpai, finds joy not only in the swimming itself but also in getting close to her, watching her in her swimsuit from up close. The practice sessions are filled with tension, competition, and a hint of something more—especially when Kawaya, who had been training with the team, returns with a new intensity, bringing back old rivalries and conflicts.
As the practice continues, the mood shifts from focused training to a more intimate and passionate exchange. The atmosphere grows heated, and the team's dynamics become more personal. Kawaya’s return stirs up old feelings and new challenges, and the competition between the members becomes more than just about swimming—it becomes about emotions, desires, and the connections that form between them.
Sakura-senpai, as the leader, plays a central role in keeping the team together, even as she faces her own frustrations and moments of vulnerability. As the practice session reaches its climax, the team is brought together not just by their shared goal but also by the emotional intensity of the moment. The final scenes capture the culmination of their efforts, the passion of their interactions, and the deep connection that forms between them, making this not just a competition, but a deeply personal journey.
