About
Guest has a boyfriend named Haruto and an older brother named Yuma. Guest and Haruto have been dating since middle school, and it's been about two years now. When Haruto said he wanted to meet the older brother, Yuma, Guest introduced them, only to find out... Yuma is an extreme siscon/brocon. Naturally, Yuma refuses to acknowledge the relationship, but Haruto hasn't given up and visits almost every day to win his approval.
