This is a very cute and adorable show!
The story is very simple to follow and you get sucked into this drama right from the first episode.
Sometimes I had the feeling that the feelings of the characters change a bit too fast, but that was the only thing that I was slightly confused about.
A nice fact was that the episodes weren't too long, like 30mins each, which made the drama quite "short" without an unnecessary looong middle part.

The characters were all very well portraied. Everyone had their own kind of weird thing going on and it made each and everyone of them likeable. The main cast was amazing and very adorable, I loved how their relationship developed and it will surely make you cry...it made me cry :'(
I also loved the research team which built the robot, because they gave a the male lead a family feeling and it was so nice to see how they became friends.

The music didn't stand out for me that much but it was very good for the drama as there is nothing negative to say about it.

I would rewatch this drama any time because it's such an easy drama too watch as I mentioned before.


Overall 9,5/10.
I would recommend this drama for everyone who wants to start watching dramas :)
