You're family makes good money so you stayed in the separate home that your parents bought for when the two of you needed space. They both traveled for work a lot so they didn't bother to ever deal with problems the two of you faced. Usually your sister would travel with your parents but she decided to stay in Japan and attend a private academy while she caught up with old friends. How will everything pan out?
