Four separate stories about what happens when swimmers stop racing each other. Haruka looking for an apartment in Tokyo feels as real as any slice-of-life moment the series has earned. The show knows these characters so deeply that it can spend an entire episode on Nitori picking out a gift and make it matter. This is the exhale before everyone scatters. It moves at the speed of actual friendship, not plot.
Four episodes capture the final summer before graduation changes everything. Haruka searches for an apartment in Tokyo with Makoto, the two navigating adult responsibilities while clinging to their familiar routines. Elsewhere, Nitori struggles to find the perfect graduation gift for Rin and Sousuke, while Momotaro's hot spring tickets become an unlikely catalyst for bringing the group together one last time. The crew gathers at Anago Hot Springs, where relaxation masks the underlying current of transition. Back at the swimming club, Rei and Nagisa throw themselves into recruiting new members, determined to keep the team alive after their departure. Gou documents their efforts with infectious energy. What emerges across these four stories isn't dramatic conflict but something quieter: the bittersweet reality of moving forward. Friendships bend under the weight of change, yet hold firm. The pool that defined them remains constant even as life pulls them toward different cities and futures. This is about savoring what's about to slip away.
