I was also expecting something different for Flash Back, but still, it's awesome IMO ♥
It's been on repeat mode since I finished listening to the full thing ♥
Eyeline is amazing too, dark electro style.
I do prefer the japanese version of Rip Off, though, it feels weird to hear it in korean after so many plays of the Jp version x)
I really liked Timeless, it's the kind of sweet ballads I like the most

손목시계 was nice too, not my fav, but still.
Overall a really good maxi single from the girls, now I can't wait to get my copies in my hands
