A really different drama where the usual cliches doesn't give you similar vibes. A MUST WATCH!!
It has its own story to tell - Love is all about your efforts, even efforts fail sometimes and so love can end too.

Yoo Tak seems like a jerk in first 2 episodes, but then before you realise you start to empathize with him as he gets desperate and helpless while trying to save his girlfriend. The same day repeats yet it is not the same as Yoo tak is also not the same. He tries everything in his might to keep her alive but gets failed everytime until the last episode which makes this drama more unique.

Its like an another loop is formed in the loop.1st loop is Da In would die when Tak's love for her will be over, but at the same time he should become happy. But he doesn't become happy and the same day repeats. In the last episode, he was happy while dying with her so the day should not repeat itself again. But another loop gets created coz Tak was so much in love with her that he was ready to die with her. so Da In should not die.
It created dilemma for Reaper girl so she changed their fate.
It is an open ending whether they would end up together or live separate lives. The hint was in the last song - "we have to walk our own paths."

really loved the acting of both L and Yoon so hee. Both make their chemistry perfect for the plot. I wish to see them again as a lead pair. (Though they acted again in Emperor of the mask, they weren't a pair.)

Songs are really amazing - music and lyrics too. I can hear them on repeat whole week.

I had watched only 3 episodes and kept this drama on hold for almost a year. I am really glad I gave this drama a second chance. Really worth it. Don't make the starting episodes hesitate you.
