I sincerely feel that this show would be better without the 2 main characters.

They're both frustrating because their issues are so simple yet they just play dumb not to try and solve them.

The issues of all the supporting characters are similar or more complicated, but they're not fools.

The show is incredibly slow, which would be fine if it was interesting.

I feel I watched the last 4 episodes only to say that I finished it and because it was just 10.

The actors though are fine, the writing and scenario is at fault.
Nevertheless,
There's too many k-drama out there to waste your time on this.
