Yanagi and Arata's encounter started off as a simple pick-up at a bar, but Arata—who balks at homosexual sex—upsets Yanagi to the point of being blackmailed into a sex-slave relationship. It is Arata's charming and innocent personality, however, that breaks through Yanagi's resolve, and deeper feelings begin to form between them. Just then, Yanagi's friend and Arata's younger twin brother, Takashi, notices Arata's strange behavior.

Just when Yanagi and Arata's sex-slave relationship starts to bloom into something more, Yanagi's first lover, Kashiwagi, shows up! Then, Yanagi's old sex-friend, Takashi (Arata's younger twin brother) stumbles across their relationship and devises a plan to get back his beloved brother. ..

After Yanagi's rejection, Arata feels his inferiority complex resurfacing stronger than ever. And Yanagi, broken by a past betrayal, gives up on love once again. Then there's Ten. Harboring an unparalleled obsession over his little brother, he schemes to keep Arata to himself. Breath volume 4 brings an accumulation of these three men's complicated ties.
