The last scene best scene in kdrama

The whole epi make my heart race non stop. The ending can explain all. The last scene is the best scene i have seen so far. No word to explain. Nam Joo Hyuk acting has give me goosebumps.

He's not dead so pay attention!

I super hate it when characters get distracted for more than a few seconds or decide to have a heartfelt talk when villains are still a threat to them. Aside from that, I enjoyed the ending, but not the fate of the poor class mate. Kudos to cast and crew!

Oh my god!

I think this has become my favorite crime thriller drama! After watching 2521, I did not think Nam Joo Hyuk would do something like this, Awesome Job!
