High school can be a stressful time for many young people. The change means a new commute, new friends, new courses, and new teachers. For Shino Oshima the change could have meant an opportunity to blossom into adulthood.

Unfortunately, things go wrong on her first day - she fails to even say her name during her homeroom introduction. From then on Shino is a part-mute part-stuttering mess. Ostracized and afraid she struggles to find her place in this new world... But thankfully for her, she finds her voice through music and some unexpected new frienemies.
