From the description, I was expecting fun and light rom-com. It started out that way and quickly fizzled out.
There was not any suspense, tension, or passion that kept my attention. The male lead was good looking, charming, a great voice, and you rooted for him through the story. However, the female lead became sullen and morose for half the episodes. I didn't feel like she was reciprocating the love of the male lead.
They set up a lot of physical comedy and situations that were super cute but not a lot of laugh out loud funny. The family and friends of the female lead were wonderful characters, but the chaebol family with all the angst was too cliche and boring.
Overall, the show filled some time, but I wouldn't call it a favorite.
