LOL, I really feel bad for Ah Yeon because I felt like she barely sang, but Taeny was fantastic as usual.
I'm scared for the people that are gonna say about Taeny overshadowing Ah Yeon. Honestly, I think that the reason why they are kinda overshadowing Ah Yeon is because they have performed this song many times before, while it's a first for Ah Yeon.

I feel bad for Ah Yeon too, cuz as soon as TaeNy entered the stage, my eyes are glued on them.
Ha Yi's lucky, she get to sing the whole song, but I don't really like her version of "U Go Girl", I guess it bcuz I get use to with the old one.
