It's basically bubblegum Jpop sung in Korean. That's why people are reminded of Orange Caramel. They started out with the same style.

On a scale of K-pop cuteness, this was pretty near the top.

I kinda like the song... but their outfits in this MV are just awful.

They've an Orange Caramel aura...

Awfull outfits, song is pretty good, but something less bright of outfits would be great. I mean after seeing the busking event of theirs, these outfits just don't do them justice.

this is a little too much
