No arranged marriage cliches of push and pull or making the partner miserable before falling for them. It was a simple drama about two people who marry out of a government experiment but fall for each other gradually while living together and finding out nice things about each other. The ML and FL are both people who do not have experience with romantic relationships, so they take their time to trust the other person.
I won't say it was a slow romance but it was more about becoming a family for each other.
The acting was nice. The actress is quite young and it is her first drama but she has an infectious smile. The side characters do not have a storyline of their own, but contribute nicely to the main story.
Jdramas for me are always about the warm fuzziness and this was the same. I'd say the first half was stronger than the second half but it wasn't boring.
