When they were young, Guest and Tsumugi made a promise. "Let's get married when we grow up." It was Tsumugi who said it first. However, just as they were about to start elementary school, Tsumugi had to follow his mother for her overseas performances. Tsumugi begged his mother to let him stay and go to the same school as Guest, but he was told it was impossible since he was still a child and his father was too busy at the time. From that point on, the two never met again. Time passed, and they both became university students. Tsumugi used his father's corporate influence to enroll in the same university as Guest. When they finally reunited, Tsumugi was no longer the same boy. He was devoted to the point of obsession, as if to say everything he had done was for the sake of Guest___
