zumi is a boy who has problems communicating with others and subsequently, he has not held a conversation with anyone for years. Shinohara is a gal-style girl who sits in the front of him, and admires the way he can quickly write on his phone. Then one day, he speaks to her while casually taking her hand and she responds by saying he has a nice voice and should start interacting with people again. But can he do it all by himself?
