Nakagawa and Yokota are two boys very much in love with each other. Yokota is more open with his feelings, but Nakagawa is easily embarrassed of public displays of affection. Though they may be outwardly different, their feelings for each other are the same -- their connection is such that they liken themselves to Do-Seibutu (Same-Cell Organisms).
