We have watched all the teasers and trailers and behind the scenes videos, but this newest video we have for you is the mother of all The K2 BTS videos. For starters, it's 7.44 minutes long and takes you through the entire journey of the drama - from the casting and first reading to shooting the actual drama. Grab the popcorn and enjoy!

Doesn't this look amazing? Also, can we please talk about Ji Chang Wook and those rock hard abs! Holy cow, is the actor looking hot or what? How excited are you for The K2? Chat with us in the comments section below :)
