There were some parts towards the middle of the story that felt slow and a bit uninteresting but I enjoyed most of it. They wrapped it up well. Contrary to the opinion that most seemed to have, I didn't see a lot of faults in Suzy's acting. Woo Bin made my heart hurt as much as he made it flutter, nothing new there. The other actors did a good job too. Overall I liked it and I don't regret watching it at all. It hit me in the feels which is what they wanted to do, I suppose, so they were successful.
