A shy Japanese girl and an American boy who only speaks English struggle to bridge their differences in communication and open up to one another!

High schooler Mutsumi struggles to express herself—so much so that she’s given up on talking altogether. In class, she freezes up and says nothing when the teacher calls on her to read out passages from the textbook.

If she can't express herself in Japanese, how could she possibly do it in English? But...what if he's the one person who can understand her?
