First time watching these two actor/actress(Kim Soo-hyun and Kim Ji-won) in the drama series together and they never disappoint me in portraying their roles. The way they convey their emotion through acting is so believable and convincing, I feel like I am watching a real couple who are not in good terms, cold/indifferent towards each other and struggling to make their married life work. I like the plot, story and setting. It's like a rollercoaster ride; it has suspense, comedy, tear jerking and heart fluttering scenes; it characterize a story of a married couple who fell out of love due to unforeseen circumstances and trying to give their marriage a second chance.
