At first I thought that this would be another reincarnation drama but it's actually rather refreshingly a time travel story with Supernatural elements. There's an overarching mystery and plenty of Comedy to balance the tragic moments. I liked how some of the characters had dual natures that the audience couldn't really understand until more information was revealed. I loved the pretend marriage trope, it's just not done enough these days.

On the flip side.... I was hard to care or focus towards the end.... Its got another jealous 2nd female lead of course, and there are still reincarnation tidbits.

Lee Seyoung can do no wrong.... and this drama was a cute watch...
