This was really cute, and ya'll have to pay attention to the audience, they make it ten times better. And the MICS ARE FREAKING FANTASTIC!! I wasn't sure if it was lip sync, but it totally isn't. I am so use to hearing pooie mics that to
actually hear them is fantastic, and you can really hear Hyuk.
