So underrated.
Hang on. Every episode get better and more interesting than the one before it.

In general, I don’t know or care much about character development, but this drama has one of the best ones.
I was slightly annoyed by Kim So Yeon's character at first, but upon second look she was a breath of fresh air, and the character really becomes better.
Park Shi Hoo has got a killer smile!
The leads are amazing, and so are their dynamics. I LOVE THEM

The instrumental OST is by Oh Joon Sung and it's really good. The songs will grow over you. And you’ll find yourself having unexpected feelings for the drama, in comparison to the ones you started it with.
I am someone who gets heavily influenced by the impression a drama gives me at first. but this drama makes up for any disappointments or bad expectations.

(I actually started this drama many years ago, watched half, and completed it now. And I love the first episodes more than the first time.)
I loved this drama. It's so beautiful to watch. The story was good, ending was good, the leads were good, music was good, all good in a K-drama way. It came close to heart.
