This drama is a poorly conceived, poorly written, and poorly executed yawn-fest. I do not understand at all how it has so high a rating. The only thing that made it worth watching at all was the supporting cast, in particular Ok-Hui and Deok-Hee: her for being a total boss and every scene where he translates what the locals mean for Jang-Yeol. They were all funny and fresh, a town full of people with different personalities and quirks. It was just that the leads were abysmal. Jang-Yeol was a jerk and a bully, Seon-Woo should have been direct and honest, and Ye-Bong was first an actual idiot that the most unrealistic part of the show is that she could have graduated from university as a veterinarian, and second such a pushover that she let herself be mistreated by friends, family, and total strangers.
The final reveal of the mystery plot and its eventual resolution was anticlimactic, and focused way too much on the uncharismatic leads instead of the rest of the residents of Mujin.
