Girl's Day has been exceeding the expectations of many, and as a rookie group, that's truly a hard accomplishment to achieve. Music fans were left speechless by the radical transformation the girls underwent for their newest release, "Twinkle Twinkle". Ahead of the broadcast, the girls stated, "It feels like we've just debuted again. We all worked so hard on this album - it doesn't feel like a comeback, but more like a debut. We're very thankful towards the people who complimented our song, and we'll try our best to live up to expectations." The girls concluded, "There's a lot of men that like our new concept, and we think it's probably because there's something that makes your heart flutter with schoolgirl outfits. We'll be working hard to show the best sides of ourselves, so please look forward to us." So check out the girls as they "Twinkle Twinkle" for you on today's Inkigayo.
