Furuya himself has fallen in love, with a nurse after his recent hospital stay. As the gang grows more jealous of the favoritism Furuya shows Shoji, they decide to reveal Shoji's relationship with Natsue. But Furuya's affection for Shoji cannot be easily destroyed, even in the gang war that erupts.
