I love it when Kdrama gets rational (aside from the super-advanced technology) and not just emotional. Guess there's a reason why they have it in 2 seasons - to which I like both. Didn't expect to see that much character developments in such short episodes so I was pleasantly surprised. It's probably the ending that I want and the ending that actually makes sense - though some might actually dislike this. I just finished all 6 episodes in one sitting and I'm about to sacrifice sleep and rewatch it to pick up on the details I'm missing.
