Kazuhiko encounters Chika while drinking water as the literature club president Shintarō Tamaki instructs them to head to the club room, where Koto announces the club will be holding a training camp in the weekend to write novels. Kazuhiko later tells Anna their plans and Anna begs to join the club to avoid a gathering with her and Sōsuke's families upon searching there is a beach near the training camp. The club arrives at the beach and proceeds to enjoy their time as Chika passes despite Kazuhiko's offer to use it to spend time with Shintarō. While Kazuhiko and Lemon head out to buy food for the club, Lemon expresses her disappointment of Mitsuki not seeing her in the same way as Chihaya, so Kazuhiko reassures her to not mope and have fun. Shintarō reads Chika's novel and is impressed with her writing, flustering Chika. As the day goes on through the night, Chika lights up a sparkler and is narrowly saved by Shintarō after directing it to her face and almost scarring herself; feeling grateful that Shintarō cares for her wellbeing, Chika confesses her feelings to him and asks him out on a date, leaving him and the others completely shocked and stunned.
