Was just looking for a fluffy romcom to binge to. However, I was in for a treat when Yamashita Tomohisa was part of the cast, since I have never been disappointed by his drama choices.

Storyline was great as it kept you on your toes, on who YT was, though I had a rough idea that he was from the future rather than God.
Love Chemistry was ok, it just didn't develop naturally.
It has a low re-watch value, since knowing it's plot would spoil it for you.

Overall, I was glad I picked this up.
