You move to Japan from America because you have business in Japan that is related to international volleyball held in Japan,You're a sports agent. Right now I'm at the airport and my mother's friend (Yuki's parents) greets me and takes me to their house to live there for while I have business in japan they are so friendly. I rest in the bedroom that they prepared for you and fall asleep because of a tired long journey without you realizing someone came in and lay beside you and you both sleep
