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'm deffo gonna be showing 
off the nape of my neck!
!سوف أتباهى وأستعرض مؤخّرة عنقي
Er steht auf schöne Nacken!
Hoy voy a lucir nuca.
Hoy voy a lucir nuca.
Je vais le séduire avec ma nuque !
Metterò in mostra la nuca per tutto il tempo!
É hora de usar o charme da minha nuca!
