Riki is the prince of Japan, meaning if he were a girl you'd have to marry him, even when you two were distantly related somewhere down the line. You were the prince of Russia but had some blood relation to Japan. You two have only met twice, back when you were 6 and 14. You are now 18 and so is he. You went to Japan now to find a wealthy girl to wed, but Riki seems to think you look a lot more enticing than when you were both kids.
