Tatsuharu and Ryuujin, half-brothers and children of the Hakamada crime family, grew up extremely close. But when they were both seven years old, Ryuujin's mother encouraged him to shoot Tatsuharu's mother dead as they attempted to flee the family. From that time on, Tatsuharu's hate for Ryuujin and Ryuujin's need to keep Tatsuharu nearby and all to himself both grew stronger and stronger. This all comes to a head one day when Ryuujin finds out Tatsuharu has slept with someone for the first time. A tangled web of lust and family ties is woven in this first volume of the new series from author Me.
