Unique drama. I have never seen anything like this, everyting is so different from what we're accustomed to. The realism makes it so it ensnares the viewers feelings and experiences, like a lot of show you would say, however, it's a natural realism where you can't say "too much".
Words weren't needed in lot of scenes, the way it was filmed succeded in making us interpret the acting of each actors. The story revolved around Lee Ji An and Park Dong Hoon, both having pitiful lives, though each in differents spectrums. In addition, a terrific ensemble cast, where individuals stories were not boring at all and were very much welcomed.
Fates intertwined, both of their existances were significants in each other's life. One taught self love, one loved.
When a happy ending doesn't necessary encompass one having their way. The aftermath of the show leaved me full of expectation, I couldn't help but imagine their future further more than what's shown. An open ending with multiple possibilities laid out for us to envision.

I especially loved the message at the end of the final episode: "you are all decent people. May you hang there until you find comfort for yourself." I felt a genuine positive message coming from the cast, producers...etc.

Occasionally, in this drama, we're taught how to relativise problematic times. They used concepts like reincarnation, implicating we'll get other chances at life. Bad things happen in life, that's nothing. If you did something shameful but you deemed it to be a not shameful thing, it's not a big deal. This lifetime, enjoy it the way it is, do your best, be kind to people which, by the way, is also displayed through the male protagonist's unparalleled kindness, he seeks justice and only justice and can't stand Lee Ji An's outstandingly unfair situation.

It is certainly by far a one of a kind drama that I doubt will ever be concurrenced. Acting on point, plot greatly developed, a purposeful cliffhanger, powerful and emotional scenes.

Tragedy is explored, they find confort in the outcome of their tragedy. So, although there isn't a happy ending per se, it is a happy life they're living.
