i usually don't write reviews about kdramas that i've finished watching, but this one is an exception; it has a unique storyline that holds a very deep and relevant meaning. i usually watch rom-com kdramas, but this one doesn't really have heavy romance in it, though i kept watching because of the lessons in each episode (which is one of the things that makes this kdrama are very good one to watch). i like how the kdrama mostly reveals the past and the after-lives of each person centered in that specific episode because it makes you understand their character and why they are what they are in that given moment. the ending was a bit disappointing but i saw it coming. overall, i enjoyed it, it got me hooked every weekend from the moment this series aired on netflix, i really recommend this!
