It's hard for me to rate this drama simply because I really enjoyed the side-stories like the brothers and their lives or Seo Yeon 's best friend and her love interest. But the main couple didn't have any chemistry in my opinion. I still found some parts of their story very entertaining but just not memorable. I also felt like the main couple was a little too repetitive.
As for the characters.
I really liked all the brothers in their own way. I thought Seo Yeon was a really interesting lead at first but after a while I found her quite indecisive and boring. Kang Woo was probably my least favorite character. I found him way too immature and even selfish in some ways.
My favorite characters were Ho Dol and Kang Woo's sister.
Overall I found myself watching it every week mostly because of the amazing side-stories.
