Toru, the son of a yakuza boss, is sent into exile on a deserted island for his own protection during a gang feud. Fiery and impetuous, he isn't thrilled to be sidelined when he'd rather be in the fight, and is even less thrilled that Mutsumi, son of the gang's second in command, is going with him. The serious, studious Mutsumi is Toru's opposite in every way, and it doesn't take long before the sparks between them begin to fly!

As Tohru and Mutsumi continue their secret affair, Tohru realizes the more they sleep together the more he gives in to the pleasure. And not wanting his lover to play the field, Mutsumi goes out of his way to keep Tohru satisfied. Unfortunately for these two, the very last person they’d want finding out about their secret relationship does. Enraged that Mutsumi would dare lay a hand on his precious charge, Domoto kidnaps Mutsumi with bloody retribution in mind!
