I think you'll get mixed opinions for the drama K2. I'm only watching it for JCW. At the start, the drama seemed promising but up until now, I still don't understand what's actually going on... The drama is a mess and it just feels like "Yong Pal" all over again. Song Yoon Ah's acting is great and I wouldn't mind romance between her and JCW. I am disappointed with Im Yoon Ah, there is just no chemistry with her and JCW (in comparison to Park Min Young & JCW in Healer), there's like an emptiness with her presence.
