This is a story that I would love to hate, but I can't because it's beautiful. It plays a trick on you. It shows you how two attention starved souls meet and find comfort in each other, so you end up wanting those two to spend more time with each other. Then you question your own judgment and morals. Do I really want two people to cross the line and cheat? The characters are so incredibly real. The people in this story are flawed, but relatable. I felt very invested in their lives. I liked all the main and the secondary characters in their own way. These could be my family members, friends or neighbors. I think that this story might be for a more mature audience, though, because it tackles a lot of issues that people in their 30s and 40s struggle with. The question of whether people have the right to be happy is not a trivial one because happiness comes at a high price in this show. Do people deserve a second chance after they made a mistake or not? Should mothers see themselves as women with needs or just parents? What constitutes a working marriage? What makes this story even more intricate is the extraordinary connection plus sizzling chemistry that the two main leads develop very early on in the drama. Also, the cinematography is beautiful. The leads will only exchange a look and the screen seems to be burning. You feel their pain and their longing. Most of the actors did a great job in this show, but I feel like Lee Sang Yoon, Choi Yeo Yin and Shin Sung Rok were especially amazing. This show might be worth watching just to see Shin Sung Rok as another cold-hearted jerk (he was the bad guy in YWCFTS). I honestly loved the story, but I can't give it a 10 because it was a bit slow at times. I generally enjoyed the slow pace, but the amount of flashbacks and fillers was a bit too much. I also found the idea of fate in the show a bit naive and too obvious from the start. Apart from that, it was a really good drama.
