The gang goes to the local pool for some fun. Hikari asks Makoto to give Taisuke a ticket because she is too shy to do it herself. At the pool, Makoto teaches Kotonoha how to swim; Taisuke is on the water slides with Hikari and Setsuna, while Sekai goes around swimming by herself. Makoto has completely fallen for Sekai, hinting her that he wants to be with her instead. Sekai keeps reminding him that he's Kotonoha's boyfriend and cannot be with her, and tells him to forget about the "practice". After everyone goes home, Makoto messages Sekai insisting that they meet. Despite her constant refusals, he travels to her home, finding her waiting in front of the train station for him. Makoto confesses his love for her and they have sex for the first time.
