Well, as the show itself quotes "Luck and Misery comes with the same face". The same happened to me while watching this drama or maybe some others may agree on this.

Things I got Lucky with:
1. CAST & ACTING - Cast of the show was really amazing to begin with and all the actors did justice to their respective parts. On second note, this show made into my PTW list because of Seo In guk and Park Bo young.
2. OSTs - The music for the show was heartwarming and definitely could heal bleeding wounds.
3. Chemistry between all the cast members was great, of course, overwhelming among leads.
4. Wardrobe - You will surely get to see eye-catching set of clothes.
5. Cinematography - It surely does make the best connect with the outlined storyline
6. Last, thing that got right in this drama was the screen-time of characters. Everyone got enough time to express themselves.
7. Philosophical outcomes of unpredictable life...

Things that bought misery:
1. It became draggy after 7th episode, I skipped through a lot of scenes though I didn't wanted to .. ?
2. I think the Story lost its essence as it evolved. I think so, because at time I couldn't feel that "Myeol Mang" was really a "Doom" and was someone who could cause disaster. Because of that it happens to be another one of rom-com by the end of the drama, at least for me.
3. Unnecessary repetitive scenes, because of them I almost dozed off.?
4. Ji Na's story - It could have evolved in better way, as it was one of those things I was looking forward to.

From someone who is about to die, to someone who is death himself story could have developed in way more better than it does now. The characters were really well written, but hoped they could have done same with their stories. I did understand deity's part, because that was all she could do without breaking rules of time.
Story was definitely intriguing and it's presentation from paper to screens was also good but It lost it's lustre half-way down and failed to express itself as it wanted to maybe. ..
If you would ask me is it a completely doomed drama? .... No, definitely not. At least way more better than shows that showcase abusive relationships. NO OFFENCE. Surely, not perfect one but not doomed one either.

Would I rewatch it?...... It is a bit draggy, for 16 eps. Maybe I would rewatch it someday, for Sa Ram and Dong Kyung .
Recommended to those who love to explore different genres and themes like me.?

P.S.: I'm here to just share my experience, like most of us does. If you want to watch it, .... Do read what others think about it, but surely experience it yourself maybe your opinion contradicts mine.... THAT's LIFE.
