English name: Because You Smile When I Sing
The pop band vocalist, Atsushi, has always been thought of by others as a "scary person" because of the facial expression he was born with and his disinclination to speak.

Why doesn’t she smile? What can a boy — a singer — with a frightful expression and no speech do to bring her beautiful smile back? Read the manga to find out!
