This was not perfect, but it was a good one. If you didn't enjoy it, then it was clearly not for you, but there might be people who will enjoy it. So we can't say that it was overall bad. I really can't say that for this drama. I don't think it was boring too, it has an interesting theme so this makes it easier to watch but it definetly has some shortcomings.

If this was made in 2015-2017 people might really love it but the screenwriting and story development lacking in some ways compared to the year we are in.
So it is normal that people will except more from this, and I am agreeing with that. This had more potential to be a really good rom-com fantasy.

If you are someone who expects the series you watch to be perfect in every aspect, this series is not for you. but if you are looking to enjoy watching the relationship between the main characters without worrying about the small details, you can watch it without worrying.
