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...
