I knew Mei was going to win the tournament the moment I saw her. I think there times when Inbu deliberately sabotaged the contest so that nobody would win, but for some reason, Mei flourished through them. I think it teaches us an important lesson. Looks may get you far, but to truly succeed you need tragedy and open-mindedness. Mei may not have been the hottest girl, but she was by far the smartest.
Inbu was convinced that he wouldn't find the one, but he was surprised too. When I see the two holding hands, I feel like a shipper seeing their OTP become canon.
