Tsumi to Kuchizuke

Yamato is sent to the gorgeous Fiji Islands in place of his brother Hikaru to meet a hunky race car driver named Kyle, a bisexual man with a well-known fetish for Japanese people. While the island Kyle inhabits is a tropical paradise, a dark cloud looms over Yamato's vacation when he learns that his brother left out a number of important details about his trip - like the fact that Hikaru and Kyle are lovers; and that since Kyle is currently injured and can't race, Hikaru wants to end the relationship. What's more, he expects Yamato to be the one to tell him! But as the two men spend time together, the more smitten Yamato becomes. Why does he have to be the one to break poor Kyle's heart?
