If you ask me to recommend a drama, Me, recommending
would be based on my closeness to that person. This drama makes you feel things that you won't dare to feel in your daily life and most people don't neither generally embrace these emotions not understand them, tbh.

A very very well written plot and fabulous plot points and twists. Won't say that this drama is adorned with cliffhanger but this story grows on you, makes you want to know more and as per louisa may alcott, that is the success of a writer.

Acting is fabulous.. specially the character Sang-Tae stole the show (i can't stop if i start so i won't)start. I have Kim so hyun better but Seo ye ji, she never stops to surprise me. The growth that she shows with each new show is immense. Damn..

Music is good too.. it did it's job of making the series more lovable.. specially the score "In silence, no one answers" makes you feel different stuff in different scenes, i.e. pretty versatile.

My rewatch value is low because I'm not much of a re-watcher.

Overall, Go for It, only if you are ready to embrace it.
