SM Family is awesome!!

I just watch SBS latest variety show which the artist have to practice ice skating for two months and perform in front if the 'ice skating queen', Kim Yuna..

TVXQ U-Know Yunho and F(x) Krystal is one of the artist..

I just watch them perform and still can't believe that they only practice for only 2 months with promotions and overseas activity..

For those who didn't watch it yet check it out below..

F(x) - Krystal

TVXQ - U-Know Yunho
