It seems as if girls always give Jun a cold shoulder or look whenever he gets close to them. Kaya provides little sympathy to Jun's plight, however she takes his hand and the next moment they are flashing back into time to 1945 (20th year in the Showa period). However, upon doing this, Jun must reveal and come face to face with a secret he's been hiding...

Kaya questions Jun and asks her whether or not she should keep up this masquerade of pretending to be a boy. In the meantime, Arashi and Hajime create some make-shift baseball gear. With all his might, Hajime hurls a ball towards Arashi, who nails it right out of the park...and breaks the weather vane above the coffee house. The weather vane, we later learn is from the prewar days, which brings back a lot of memories to Arashi and Kaya...

On their way back from buying a bunch of watermelon, Hajime and Jun decide to take a break at a nearby Shinto Shrine. They spot a vending machine but only have enough money to buy one drink. Hajime suggests that they share it, however, Jun thinks that it would be like having an indirect kiss with him and refuses. Hajime gets the wrong idea and tries to force Jun to drink it, causing them to tumble down the stairs. They both get up without injury, but now they're in each other's bodies...
