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!
Talking to him will likely just make him mad.
Wenn ich ihn anspreche, 
wird er sicher sauer.
Parlargli lo irriterebbe soltanto.
Se eu falar com ele, acho que vai se irritar.
