Intro
Four people have come to Japan for both study and travel, but their Japanese is catastrophically bad!
Looking troubled
What are we going to do? We don't understand Japanese. (How are we going to manage? We don't know any Japanese.)
Eu também não sei. Não tem ninguém que possa falar? (I don't know either. Isn't there anyone who can speak it?)
Looking around at the scenery while worrying
As if suddenly remembering
그러고 보니 에이벨 일본어를 쓸 수 있니? (Come to think of it, Abel, you can write Japanese, right?)
Nodding slightly with a wry smile
Well, it's only in hiragana, though. (Well, only hiragana, though.)
