It's very different from your usual rich good looking male and poor brainless/helpless girl.
It's a really good watch. The length and pace of story development is great.
It talks about difficulty of surviving in the work force/society as a 30 year old female, one's pride and search for perfect/materialistic approach vs love. also the idea of pet/animal is better than human company.

I think the length of this show is perfect. 16 episode is a really good middle length.
The usual 11 is way too short for my liking.

I usually judge a show pretty harshly and there's not many I like. I've watched Jdrama, Kdrama, Cdrama you name it and this one on the top of my Rom-Com list.
It's a light hearted warm drama and it delivers that. If you watch it for what it is and don't judge it with all the real life logic and common sense then it's a really good adaption.

You'll like it if you are looking for the following:
pretty or handsome cast
living together
older female with younger male
personal development
challenge in society as a female in their 30
growing up & becoming responsible
comedy
finding love
