The story follows Nishikata and Takagi as they join Nakai and Mano at a water park. Nakai and Nishikata decide to go down the big water slide together, which disappoints Mano. Mano explains to Takagi that she's too nervous to be alone with Nakai, and that the two had agreed to ride the big slide together, following a rumor that couples who ride it together will fall in love. To support them, Takagi decides to leave Mano alone so she can spend time with Nakai. Later, Takagi finds Nishikata wandering aimlessly, and they buy juice together. After seeing Nakai and Mano go down the water slide together, Takagi challenges Nishikata to catch her on the way down. Although he accepts and nearly catches her, she tells him the legend of the slide, causing him to purposely slow down at the exit. At the end of the day, Nakai and Mano ride off on a bike while Nishikata and Takagi take a bus home. While walking to the bus stop, they agree to return to the water park together in the future. In a post-credits scene, Nishikata is seen sleeping on the bus home with his head on Takagi's shoulder, who looks flustered. "Water Slider" continues to showcase Takagi teasing Nishikata and the deepening feelings between them in a lighthearted and humorous manner.
