It's not a light and airy kdrama. One bad thing happens after another. Even the "good" people aren't exactly saints. Some actions seem inexplicable at first because they aren't explained until later. But the acting is superb and ML and FL are great together. The ending didn't go in the direction I was expecting but it was still satisfying. It does have a few tropes you see in all kdramas but it's not over the top. And it's only 12 episodes so there's not a lot of filler. It's worth a watch.
