Summer vacation is coming to a close. Wakana received an SOS from Marin, who hadn't finished her homework, so he ended up helping her study at her house. They later realize that Marin had forgotten some math drills at school, so they go to get them. While alone at the school, Marin and Wakana make plans to go to a summer festival together. And when that day finally arrived...
I don't have swimming class, 
so I've never gotten to go in.
ليس لديّ درس سباحة، لذا لم أتمكّن
من المجيء إلى هنا أبداً
Ich hab keinen Schwimmunterricht
und bin zum ersten Mal hier am Pool!
Es la primera vez
que entro a la piscina.
Es la primera vez
que entro a la piscina.
J’ai pas cours de natation,
j’étais jamais venue !
Non sono mai entrata qui
dato che non faccio lezione di nuoto.
É a minha primeira vez na piscina,
 fora das aulas de natação.
