I love the begging and I love the end.
I was so happy because it have a different approach to the whole back in time and revive stories.
The thing is, what a mess during the middle. It gets so repetitive, it gets confuse and it has a lot of unnecessary little plots.
It could have been amazing, but I had to lower the rate because I just got really tired during the drama. What a shame.

Good things: The FL is amazing. The production is definitely beautiful. Very interesting story. Good end.

Bad things: The story loses its track during the middle. I'm not sure if the ML it's the best for the role, he is definitely handsome though. The other characters are just there...
