Overall: I was really enjoying the chemistry in the first 4 episodes but the last 2 didn't work for me. 6 episodes about 35 minutes each. Aired on WeTV https://wetv.vip/en/play/x9f8tbtrynespbk-Memory%20in%20the%20letter%20(Uncut%20Ver.)/x0048wdyxbh-EP1%3A%20Memory%20in%20the%20letter%20(Uncut%20Ver.) A spoiler comment with additional thoughts.

What I Liked
- unique premise
- mystery aspect
- sweet moments
- chemistry

Room For Improvement
- though I'm normally not a fan of montages to show time passing, I think they needed one because it seemed a bit rushed for what happened at the end of episode 1 to happen
- love rival (this kept me from fully investing in the couple)
- Christmas music
- the dad's redemption arc was poorly done
- never explained exactly what happened to the mom, was it an accident, how did that happen???
- unrealistic things i.e. lugging something up to the roof and leaning on it without worrying about it tipping over, something taking only 5 years which for that kind of case would be a person with much more training/experience, no one really concerned over something, etc.
- awkward kiss in episode 6
