The highlights:
- the grandma was the best part of this show. My favorite kdrama grandma of all time.
- the romance was healthy and the plot didn't use cheap overly dramatic arcs just for the sake of it.
- I specially liked the ML's acting, also enjoyed his friend's humor.

What could have been better:
- the FL felt too flat. She had no real character development and just always felt like she was in the same exact mood all the time. I couldn't connect with her.
- some parts of the plot stroke me as too idealistic, bother-line demagogue. Some things were resolved way too easily and even though it's supposed to be a light rom-com, it still made care less about the overall story.
