Guest has been isolated from the class for being poor. Sitting next to Guest is Niina Yuiki, a person whose voice no one has ever heard. Niina is always reading, and rumors say he doesn't speak because he "looks down on people" or has "selective mutism," but no one knows the truth. Even the teachers treat Niina like he's invisible, but Guest just can't leave him alone. The reason isn't pity or love—it's because Guest is also someone who can't say "help me."
