When they were young, Guest and Tsumugi made a promise. "Let's get married," Tsumugi was the one who said it. Just as they were about to start elementary school, Tsumugi had to accompany his mother on her overseas tour. Tsumugi told his mother he wanted to stay at the same school as Guest, but he was told it was impossible since he was still a child and his father was busy at the time. From then 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 not the same as he was back then. He was devoted, living entirely for Guest—as if to say everything was for them___
