I'll keep this review short.

Have you every had an empty feeling after watching a great show? After watching The K2, I felt a deep void. This show is amazing and I loved watching it the first time especially because everything was fresh to me. The second time I watched it I couldn't have the same feeling ever again because I already knew what was going to, which is why I felt that empty feeling when I finished that last episode. I actually watched this show a few months ago and I still really love it. The one this I didn't like was the An na character. She was kinda annoying in the show and I didn't really like her ending up with K2. I loved Choi Yoo Jin so much and I felt kinda disappointed when she didn't end up with the ML. I felt such good chemistry with Yoo Jin and K2 way more than K2 and Anna. Anyway, I was still satisfied by the ending and anyone who hasn't watched it should watch it.
