Girls' Generation's YoonA displayed some emotional acting skills in new teasers for 'The K2'!

In one teaser, YoonA goes into near hysteria as she screams at Ji Chang Wook's character multiple times to shoot a woman in the head. It's a side of YoonA we haven't seen before, and it will be interesting to see more of her acting in this anticipated series! In the other teaser YoonA is calmer, ordering Ji Chang Wook to not die. Makes you wonder exactly what sort of relationship the two have in the drama, doesn't it?

You will have to tune into the drama when it premieres on September 23!
