Okay, so first off I want to say, all together I really did enjoy this drama since the story and the hospital environment was a nice change from watching a lot of ancient dramas. Bu then to the thing that I don't really get...

The unnecessary fighting:
The main characters were fighting through the WHOLE FREAKING DRAMA. Yes, I know married couples do fight with each other and so do all people, but from time to time it was almost unbearable to watch. They fought about everything, and I mean literally EVERYTHING. But the problem wasn't just with the main couple, but also the fighting at the hospital and everything.

The ending:
I've seen a lot of comments about how the ending was since who doesn't love running to they're loved ones, but my problem with this is it left a lot untold. It was unclear why the male lead was working there, did he enjoy it? Did the the parents actually ever meet each other? The whole drama was so much fighting between the female leads father and her husband and herself. I find it pretty sad that when the father finally accepted the marriage they never showed the wedding and anything. The drama literally had 42 episodes and some of the scenes were made almost a little too tiringly long, but then again the ending was speeded up and not really the ending you are looking for after so many episodes.

In the end i did really enjoy it, but it could have been better. I'd still recommend it if you have the time
