First things first:
This is one of the most underrated dramas I've seen so far. I'm pretty sure due to poor ratings and views the drama was cut down to only 12 episodes because no other drama has such an unusual number of episodes. And all of that because the majority was too impatient to give this slow-paced drama a true chance.
It is a bit confusing and odd in the first two episodes and because you don't understand what is going on at first it may also come off as boring.
But in episode 3 (4 at the latest) you start to realize that this show is anything but.
It's comforting, warm and I felt like I was on a trip of emotional healing myself instead of just watching the show's characters heal.
This show is like honey on a soar throat. The glue for a broken heart. Wellness for your emotional health.
Definitely one of my faves.
The minus point is for the weird first two episodes and the fact that I didn't quite understand the female lead's behavior in the final episode (probably because the ending was kind of rushed because of the cut down number of episodes and them trying to put everything in one final episode without having the time to explain every action perfectly well).
