I don't quite understand the low rating, but I enjoyed watching this.

First, loved the story. I like how the plot unfolded piece by piece with each episode. It kept the series really interesting. I never got bored or thought of dropping this at any point.

Incorporating children into the series also lightened the tone subtly, which was nice.

Characters and acting are both good. No cringe-worthy moment.

If there are areas to nitpick, I would say:

1. The romantic element could have been better.
2. The pace was rather slow althought this was not a problem for me
3. There were a bit of flashback, althought not excessive.

All in all, I recommend for anyone who likes a good story.
