^ I wasn't a fan until after Jin came back and was already doing activities full-time again. Knowing what we know now, watching all the pre-hiatus video made me go, "Maybe he really needed that break" because he just wasn't looking so excited.

Once he got back, I think he realized that he has a lot of responsibility to the group and the fans. To a degree, I think he was too full of himself prior to the hiatus. Now he seems more humbled and is actually enjoying being an entertainer again.

As for Ueda, I think he's just introverted, therefore quiet. KAT-TN call him on it once in a while. He doesn't really catch my eye most of the time but I love him all the same.
