Yutaka Aoi is sweet, sensitive, and loves singingâ¦ so much so that he cant help but be brought to tears whenever he listens to beautiful music. He also has a talent few boys have: he can sing soprano. So when Yutaka overhears his middle schools choir group perform, he cant resist joining in. Inspired by the angelic sound of Yutakas voice, the choir eagerly accepts him into their ranks. But when Yutakas voice begins to change as he enters puberty, the journey ahead will be one of self-discovery and reflection for not only himself, but also for those around him.
