I started to kind of like Koki (though I know nothing about him) when someone on my friendslist mentioned that he "ruined KAT-TUN's bad boy image by supposedly doing nice things for elderly people". That's the kind of rebellion I approve of. ;P

I tend to like/approve of random people from other groups (K8's Maru, for example) without ever becoming their fans, so I think it's OK to like Koki. ^-^
