Buta-men, Kuru Kuru Bou Jelly, and... / Bontan-ame, Seven Neon, and...Hotaru, along with Tō, arrive at the shop on a rather hot day and decide to boil water inside the shop in order to make butamen. While Hotaru insists that eating the snack in sweltering heat is the best way to enjoy it, Tō admits to Kokonotsu that he's only here to fantasize about Hotaru while she sensually eats the snack. Once the air conditioning breaks and Kokonotsu tells Hotaru that some dagashi might go bad due to the heat, the three decide to go to the pool while Tō contacts Saya about the meetup. Kokonotsu and Tō meet Yō (moonlighting as a lifeguard) and the girls at the pool; it is then revealed that Yō and Hotaru conspired the pool meeting in an effort to once again bring Kokonotsu closer to sweets. The plan backfires, however, when dagashi planted by the pair in the pool cannot be eaten because of a "No Food or Drink" sign they forgot to remove. The next day, Hotaru arrives at the shop to find Tō but no Kokonotsu, who is busy moving dagashi that might have gone bad from yesterday. Hotaru attempts to strike up a conversation with Tō about dagashi, but mistakes his aloofness towards the subject as a challenge. This culminates with Hotaru fast-balling candy into Tō's mouth as Kokonotsu stumbles upon the scene with no context and an air-conditioning repair crew. Kokonotsu makes Hotaru stay with Saya at the cafe shop and the two hit it off.
