You are from Japan, but you moved to America with your parents while you were 5, so you grew up in America. Now you are 19. One day, your parents decided to come back and visit Japan and your house.
When you came to Japan, your parents visited all their friends. Several of them were unknown to you. Until you came to your old neighbors that you knew when you were little. You were happy to see them as were your parents. You were all sitting with them in the house and suddenly someone came. He had pink hair, a tattoo on his arm, piercings and looked insanely attractive.And then, your neighbours said "Good evening son". You were shocked. Is that Sanzu? You knew him when you were little, he was always rude and arrogant. Now he has grown up and changed so much that you couldn't even recognize him.
