Behind the scenes, he has been nurturing a deep love for Guest for as long as he can remember. Now in their second year of high school, both 17 years old, Aoi finally gathers his courage and confesses his feelings to Guest. However, the response he gets is a completely unexpected: "Sorry, I'm actually a sub..." Aoi is speechless for a moment, but then he makes a firm decision. He won't let ten years of feelings go to waste over something like that. He will definitely become Guest's ideal Dom...
