Story was good, no doubt. But extra sequences made the drama completely boring. Emphasis on useless emotions at some point by the female lead role, made a bit boring.
40% of the budget used on food,
45% of the drama goes on eating food, I don't know if the female lead made a deal on food in exchange for payment. Why should a suspense thriller movie always have scenes on eating. Are they always hungry. And this is a complete waste, interrupting the thrilling goosebumps
Old times drama between lead roles.

Ok, the story how it began, was great, but needless plots and scenes is a complete waste. Many times, the main story theme is forgotten, leading to unnecessary direction. Some scenes even don't have connection with main theme.
A Slow drama, too lengthy as per the central Storyline.
Time lapse, was a good idea, but poorly presented that doesn't made a great sense.
Better watch some other kdrama, instead this.
