hmmm i don't really remember actually.
but at that time when they debut and what not, i wasn't really into girl groups.
but now, i'm actually liking them and other girl groups, but i really like them more because they seem more pure and adorable. haha.
anyways, my sister was actually into them, and i kind of forgot about them, until they came back with a member that had left and two new members added to the group, and then there was a bunch of talk about rock u, so i looked it up, and then got into them since then. haha.
