Yokoi-san gets closer to Seki-kun as he's trying out glasses in class. She starts to think that the glasses are so he can see during class... but that leads to a huge misunderstanding!
So maybe this means he's 
actually going to study?
Will er etwa am Unterricht teilnehmen?
¿Eso significa que ahora sí 
quiere tomar la clase en serio?
¿Eso significa que ahora quiere
tomarse en serio las clases?
Se serait-il enfin décidé
à suivre en cours ?
Significa quindi che ha intenzione di studiare?
Então ele finalmente vai estudar a sério?
