Of course sad end :(

 Keren:

Maybe they will meet again in Switzerland, where they met for the first time. I just hope the time skip won't be too long, and I hope it won't end with them staring at each other.

I can see this happeningㅠㅠ One of those open-ended endings where X time has passed after a sad parting scene.

I’m torn between the happy and sad ending. It would make sense for a sad ending because of the two countries and both would want to be in their native country. However, I could also see a happy ending with Switzerland possibly. It’s not unheard of for a show like this to have an unhappy ending but I think it’s more likely that they’ll get the happy ending. I could also see the unification ending because she would want to fulfill her promises to the guys especially the one who loves K dramas

I wonder if the reunification would take place in the future (10 or even 20 years later but the leads not forgetting each other).

Sad :( therfore wont watch it such a waste of Hyun Bin

The drama could still have a happy ending, only 6 episodes have aired so far. 

My only wish for this serie is really hope that they are going to be together <3

I hope they have reunification so Kim Ju Meok can have lunch with Choi Jiwoo as promised. That would be hilarious  

That’s the one thing I’m hoping for the most aside from the romantic leads getting a happy ending. I really like the four sidekicks-even the grumpypants Soldier.
