it's a bit hard to find action movies that are worth it....it's really worth watching it, it's worth wasting your time to watch it as an action, it's superb at the beginning it was a bit boring but it's getting more and more interesting
I really liked that there is also talk about true friendship with the two sacrificing their lives for each other, gorgeous, a little sad, but I really love it

Honestly, I've watched a lot of action series movies, but this is really something to tell us how much action is in this kdrama, I honestly would really like to forget that I watched it and watch it again because it's something great
