Cha Tae Hyun plays the main lead and it is like a rollercoaster of emotions just like Along With the Gods: The Two Worlds. Lots of crying but full of hearth warming moments and good laughs scattered throughout the movies. Endings are fascinating, as well.
Both leading actors and actresses give off the same vibe. Similar timid, innocent girl and arrogant, workaholic, obsessive heir. Even the development of the story and the relationship between the main actors and actresses are very similar.
