Dousaibou Seibutsu.

Two boys, Nakagawa and Yokota, share a mutual affection for each other. Yokota openly expresses his emotions, while Nakagawa feels uncomfortable with public displays of affection. Despite their differences in how they show it, their feelings are equal, and they describe their bond as that of Dousaibou Seibutsu—Same-Cell Organisms. The work includes seven stories, such as "I Love You," "Lullaby in My Hand," "The Letter in the Attic," and "To Make an Angel," with additional material from BE×BOY GOLD 2000-04 and a 1998 version of "To Make an Angel."
