I really liked the drama and my ratings say it but I am here to rant about the flaws. It started so nicely that every weekend was something to look forward to and seriously the first half was so amazing that I rewatched some scenes on weekdays but what happened in the 2nd !!! It was just not it. There were twists but they felt hollow.
The main selling point is the main couple yet it feels that some of their story is incomplete especially the separation and 3 years of marriage phase. THIS ALL HAPPENS DUE TO UNNECESSARY ATTENTION TO OTHER CHARACTERS WITH THEIR UNNECESSARY ARCS. Seriously who cares about the romance of the aunt? How can you spend more than 30 min on building some out of the pool things and give less than 5 minutes on the main couples separation reasons and justification? Till now no good explanation is there on the couple being separated just one that a child was to be had and that too is a mystery. Like they could have actually utilized that aunt to bring back the main couple together through her own 3 divorces or something like a wise woman but I feel the character is just not utilized properly and given unnecessary screentime.
Same goes with the little brother. Just why does he feel so hollow?? He maybe a comic relief and devoted type but just feels way too empty. There is no character development for him frankly just sudden bursts of fatherhood and manhood.
The evil mother is still not clear to me to this day on her actual past that motivates her. Eun Sung is given good presence but his obsession could have been more elaborated. The orphanage thing is also mentioned but not properly worked out.
This unnecessary attention distribution is why the PACING OF THE SHOW IS ALL OVER THE PLACE. It is good to have characters but if you keep switching this much from once character to another obviously anyone would feel the link getting lost and not connect with any character and feel bored and dragged. Come on you can do better than this.
