This is one drama that surprised me with the fact that it works so well.
Shin Hye Sun's acting does not surprise me. Her crying scenes have always been so natural and her acting like a teenager with an adult body is interesting to watch. There was definitely also chemistry between SHS and Yang Se Jong.

There were sad moments that is masked by the female lead's optimism and also moments where the male lead really portrayed being in seclusion so well due to his regrets. This is a healing drama that helps two biologically 30 year olds to grow and mature as they have been stuck in time when they were 17. I liked the fact that they tied loose ends and gave the leads the ending they deserve.
