This drama is very intriguing and special in its own way.
The plot is not so special since nowadays there are tons of other k-dramas where the main character can go back in time, Twinkling Watermelon, The Atypical Family, etc.., but the thing is how the whole show is put together.
The actor and actress were the perfect pick, they complemented each other perfectly and made the drama a hit. Every episode made you want to cry from Kim Hye-yoon acting and every episode made you want to pass out because whenever Byeon Woo-seok came on screen.
It's true that some parts of the episodes are boring but it is all worth it for the ending.
Overall I am very happy with this drama and it is by far my favorite k-drama.
