Seobaby and Krystal!
They did a pretty good job, full of youth and clear skin :P! I think it would have been more interesting to see YoonA or Sica with Krystal, but the concept of two maknaes is great too!
Though… did their face seem unnaturally/overly white to anyone else? Should have put less make up on… the key to make up is to look like you didn’t use any!
