In order to achieve their respective goals in swimming, which they love, they continue to endure the guidance of strict coaches. Stretching like dementia, breathing exercises like Irama, fluttering foot exercises like leg jobs, artificial respiration like kisses, and outdoor FUCK to train your lung capacity. Surrounded by the blue sky and the sea, the swimming club members seem to have grown both physically and mentally.
