Fresh from a break up with his boyfriend, Kanou is depressed, and he wonders where things went wrong. He thinks of committing suicide by walking straight to the upcoming train on his way to work, but a high school student stops him. Since then, Kanou seemed to always run into the boy who smiles or greets him at the train station every morning. Kanou dubs his savior 'Campanella,' a character from a book he read. Meanwhile, at work, Kanou continues to work hard as usual and finds himself being drawn closer to his boss. Will his new-found feelings bring him happiness, or will it end up in tears again?
