IANHWANAN

After their troubled teen years together, Won-Seo thinks he'll never see his adopted brother, Joo-Hyeon, again. So his life is thrown off balance when Joo-Hyeon suddenly returns to Korea as an adult and shows up at Won-Seo's door. Not only does he act suspiciously playful around Won-Seo, but he even seduces him on his first day back, triggering Won-Seo's repressed feelings of lust and obsession. Even as their bodies mix, there's a question lingering in the air: What could Joo-Hyeon want with Won-Seo after all these years?
