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...
We got in trouble for not 
coming here in our uniforms.
وقعنا في ورطة لعدم قدومنا إلى هنا بزيّنا الرّسميّ
Der war ganz schön sauer,
weil wir keine Uniform tragen.
Nos regañaron por no venir en uniforme.
Nos han regañado
por no venir en uniforme.
On aurait dû venir en uniforme.
Siamo finiti nei guai
perché non indossiamo la divisa.
Levamos uma bronca por
entrarmos sem uniforme.
