Still in pain after being stood up a year ago, Junichi decides to skip the Founder’s festival when Masayoshi catches up with him and invites him at his house. A year later, Junichi decides to change himself, and he starts by volunteering as Tsukasa's assistant for the Founder's Festival committee, to everyone's surprise. Junichi is amazed with Tsukasa's work ethic and the work she does. While being locked in the storage room, Junichi tries to get to know more of Tsukasa until Miya and Sae arrives. On their way home, Junichi meets her older sister Yukari on the way but Tsukasa shows displeasure and hurriedly excuses herself and drags her sister home. The next day, despite Tsukasa being busy substituting swimming classes for Kaoru and Keiko, she is able to help Junichi deal with problems concerning the festival. Later that afternoon, Junichi finds a notebook on the classroom floor. As he tries to find the owner's name inside it, Tsukasa, still in her swimsuit, suddenly arrives.

Junichi and Kaoru are picked up by a passing truck who's driver sends them to a nearby hot spring inn with a bus stop. As they both start to argue over who's fault for missing the bus, the truck driver comments and gives some advice for the couple. Arriving at the inn, both of them realize the inn looks haunted and with only both of them the only customers, Kaoru is scared of being alone that she asks Junichi to accompany her even at the baths. After having a meal and heading to bed, Kaoru confess to Junichi that she set up this trip as she wants to know where their relationship is heading but Junichi has fallen asleep. The next morning, Junichi learns he left his coin purse at the bus stop, leaving Kaoru to use almost all her money to pay for the inn bill. Both of them argue again with Kaoru blaming Junichi for being careless and him blaming her for on always buying limited-edition snacks, which both of them refuse to talk with each other to the bus stop.
