Take notes because this is perfect execution on all fronts.

Choi Yi Jae, at the lowest point of his life as he sees it, chooses to end his life, only to meet Death who is angered with his flippant attitude towards her and is now putting him through a punishment of undergoing 12 reincarnations, each person on the brink of death, Choi Yi Jae is given the chance to save their lives. If he succeeds, he gets to live out the rest of their life, if not, he goes through his trial again.

And punishment it is because he has to not simply find a solution to prevent their imminent threats, but also go through the feelings of sadness, betrayal, pain, helplessness and more when his reincarnation eventually succumbs to their situation. Choi Yi Jae nevertheless goes through his lives with his personal agenda and goals, but with each passing lifeline, his attitude towards life slowly shifts as does his personal goal.

It's such a great beginning honestly, not just with the story, but the execution and the cinematography. And most importantly the cast. Wow. Seo In Guk is honestly such a good actor, plus each of the actors who play one of the reincarnations is brilliant at picking up on the little quirks that Seo In Guk brings to his character so that it looks like each of them is actually Choi Yi Jae. Just the guest cast is stacked, Choi Si Won, Sung Hoon, Kim Kang Hoon, Jang Seung Jo, Lee Jae Wook, Lee Do Hyun and that's just the first part. I haven't even gotten to Park So Dam yet, every expression and dialogue of hers carries the weight of her character. Every single one of them just brings something great to the table.

This was a really good 4 episodes, the plot honestly wrote itself and I can't wait for the next part.
