A Silent Voice Vol. 3 by Yoshitoki Oima

"ARE YOU AFRAID OF HER?

Shoya's decided to do everything he can to make up for how terribly he treated Shoko, his former classmate who can't hear. But more than the challenge of learning to communicate, it means facing a past he thought he'd left behind forever. Now a reunion with old friends will transform Shoya, and his relationship with Shoko."
