After a swimming lesson in PE class, Ryōta and Yūki struggle with washing their eyes as they are scared of water spouting from the tap they have to use. Having had to deal with Ryōta complaints of eyes stinging from the chlorine, Chika intervenes and she manages to trick Yūki into washing her eyes. However as she tries to force Ryōta to do the same, their friends cause Ryōta and Chika to have an accident. In trying to take revenge Ryōta accidentally causes Yūki to fall into the pool and in apology, he must give her his clothes so she can change out of her wet ones.
Después de una lección de natación en la clase de educación física, Ryōta y Yūki luchan para lavarse los ojos, ya que tienen miedo de que el agua salga del grifo que tienen que usar. Chika interviene y se las arregla para engañar a Yūki para que se lave los ojos. Sin embargo, mientras intenta forzar a Ryōta a hacer lo mismo, sus amigos hacen que Ryōta y Chika tengan un accidente. Al tratar de vengarse, Ryōta accidentalmente hace que Yūki caiga en la piscina y, como disculpa, debe darle su ropa para que ella pueda cambiarse de su ropa húmeda.
