I'm glad to see her smiling. Watching Kananan cry in that video on Youtube (on the S/mileage channel) just about broke my heart. What was that all about, anyway? I take it they were criticizing her dancing.
It was a tactic for selling tickets for the S/mileage tour. Tsunku commented on her presence in the group; telling her to be more sexy, and have a bigger presence in the group. She's fine. :)
