There are two separate narratives featured in this manga. The first one, titled Hoshi no Harmony, spans two chapters and revolves around a girl named Yukiko, who blindly follows the commands of others, and a boy named Wada, who is frustrated by how her peers take advantage of her innocence and kind nature. He tries to awaken her senses and bring her to reality.
The second narrative, covering four chapters, centers on Mayuko and her life. Mayuko had once pined for her cousin, but vowed to never love again. Everything changes when a senior from her volleyball team, Sugikake, begins teasing and harassing her.
