I try not to rate things a 10 but this drama definitely deserves it. *MINOR SPOILER ALERT* The story is amazing and I have never heard of a plot done so well that causes so much emotion in the viewer. You fall in love with all the characters even her douchebag ex boyfriend and friend. Don't get me wrong her storyline of not wanting intimacy with men being down to seeing her mum kiss another man was a bit weak and her attitude will annoy you lol but you get over it as JJY's storyline becomes a bigger deal and the way she stays by him through it all. I love the fact that you as a viewer begin to think as the drama goes on 'hmmm somethings not right about this guy but I can't put my finger on it'. Acting/Cast....one word AMAZING!!! The tears, the genuine laughs and the smooches are so realistic you cant help but laugh and cry with them. Uncle Jo's character is a ray of sunshine in the otherwise deep storyline which brings some lightness to it. Hae Soo's mother does become a bit of a thorn in the viewers side as she tries to protect Hae Soo in the end but I guess you can understand where she is coming from. The relationship between JJY and Kang Woo is so deep and well done, it was so sad to see KW go in the end. Music....I play this OST (also can be found on Spotify) all the time. Absolutely love the songs and they all fit with the various scenes. The music director for this show knew what he/she was doing, they knew when to play the right music and when silence was necessary. LOVED this OST. This is a defo rewatch. 10/10 Watch it, you won't be disappointed at all.
