This drama is not so bad, but not so good either. I suppose, it depends on your taste.

Honestly, I didn't like the FL, because other than being good at work, I didn't find her an interesting person. But I think I could say the same about every character, since it is an office-based drama.
I think I have the writer to be blamed, because in the whole story, the best character was the child, who's a secondary character...
Both male lead and female lead didn't have (my humble opinion, much chemistry or compatibility. And sadly, they didn't feel much real to me. Their romance felt forced somehow... And I didn't like that.
The female lead worked hard, yeas, but why?... I felt she didn't have depths, although the writer tried to create it by giving her one family conflict with her mother.
The main male lead was better, at least he had friends and sisters and a niece. I like the relationship among the siblings the best, and I think that is what saves the day time after time. I like dramas where family matters.
But overall:
I found the story a little bit boring and I confessed I did a lot of FF...
But that is also why is good, you can binge it very quick...

So if you are looking for something easy to watch, and the romance of at least one very handsome couple....This may be good enough for you.
