In the first kh we all knew (or thought) that Riku was going up against Sora because he loved Kairi but then at the end knew she loved Sora so gave up on her then when Namine showed up in CoM we all thought she would end up with Riku but actually is with Roxas. So Riku ends up alone, seems like he's the one always sacrificing himself for everyone else while all the other guys have someone. Doesn't seem fair to me
