Synopsis: Vocalize

Sera Seo is a high school girl who has a complex about her low voice. Ever since being teased about her voice in junior high school, she has been unable to say what she thinks out loud and has been unable to fit in with her class. In Sera's class, there is another boy who stands out from the crowd, Takeru Narukami. She thought that Narukami, who always wears headphones, was a loner like her, but when she saw Narukami singing behind the school building during lunch break, her feelings changed.
