Bentio Inimota left middle school behind—and with it, any desire for friendship. After being quietly abandoned by his best friend, Bentio chose isolation over heartbreak. Now, in his first year of high school in Tokyo, he keeps to himself, never speaking unless necessary.

That is, until the day he saves Shizune Nozomiya, a quiet girl who cannot hear and struggles to speak. After pulling her out of the path of an oncoming truck, Bentio expects to return to silence. But Shizune’s tears—and the small, brave “thank you” she whispers—stay with him.

As he starts to walk her home each day, a fragile connection blooms between them—one built on small notes, soft smiles, and shared silence.

Just as his heart begins to open, the past returns in the form of Magiru Satawa—the same girl who broke him. When she joins their class and slowly recognizes the boy he’s become, Bentio is forced to choose: confront what hurt him or protect the quiet peace he’s finally found.
