This surpassed my expectations. It was funny, sweet, and emotional, with great acting by the two main leads, and her parents.
From the synopsis here and on Netflix, I started this thinking it was something I would be able to watch over time, not binge. That quickly turned out to not be the case!

Fangirling took a backseat in the story as it progressed, and the story turned out to be more of a healing drama, with mature, healthy relationships - both romantic and family-wise.
It was so refreshing to see a couple in a drama that actually were communicating well with each other, as well as being considerate for the other person. I would also say they had rather good chemistry.

What I did not quite like was the character of the first director (Cindy's mum). She was just overly exaggerated - made me cringe. That character could still have done it's part in the story without being so extreme.

I saw some comments about not seeing the point of the second ML (mr Nam Eun Gi), but I thought he played a part in the story, without it taking too much space. I would say that his story, together with Ryan's, showed two different "versions" of a similar issue (difficult to explain without giving away possible spoilers).
If anything, her friend's employee/artist was the character that felt a bit unnecessary to me, even if he didn't take up too much of the story.
