STRENGTHS
- Unique storyline presented in an unpredictable way; makes you curious about how it would end
- It has Ra Mi Ran, Kim Hyun Joo and Kim Myeong Min; with their superb acting skills, who would not get drawn into their characters' emotions?
- It also has EXO's Kai (more comments below)
- Excellent acting from the supporting cast, especially by the child actors
- It has a non-toxic mother-in-law character (yes, I consider this a strength lol)
- 'Monochrome' (OST) will stay in your head even after you have completed the drama

WEAKNESSES
- Flow of story can be dragging at times; frustration may keep you from completing the drama
- Once you get invested in the story, some scenes and situations may crush your heart and leave you tearful
- Ato (Kai's character) has his own charms, but he may at some scenes can be either annoying or cringey or both
- Some supporting love lines were introduced but were not paid attention to in the end

SOME COMMENTS
- At a certain point in the drama, I found myself asking, "Who should Song Hyeon Cheol end up with?" With logic, the answer is simple, but the struggles of the human heart is not a math equation, more so, the emotional consequences of a person's choices. (There is actually a Song Hyeon Cheol [C], if you ask me.)
- Some may think this is like a "ugly wife vs. pretty wife" kind of story, but the choices are not really between those two words.
- Memories may reside in the mind but it is the heart that makes meaning of them.

RECOMMENDATION
This drama is worth your time. I suggest you watch it, especially if you want to see a different side of Ra Mi Ran after watching Reply 1988 or Black Dog.
