I had high hopes for this drama because of the male actors initially, but so far, all the actors have done a good job. The story and direction of the drama is lacking.

Unfortunately, it is your typical non-communication/mis-communication tropes and for 20 minute episodes, the flashbacks are just too long and unnecessary. It is a 15 x 20 minute episode series so why do we need reminding of what happened 60 mins ago?

This drama could have been better, it might be redeemed in the last 3 episodes. If it is I'll be back to revise my review.
Flashbacks aside, it is still mildly enjoyable and short enough to binge watch.

I think the drama should have been fleshed out a bit with back stories and better developed side stories.
