When I first started this show I expected a storyline where the FL would go back in time to save the ML and help him deal with this mental health problems. However it quickly moved in another direction with numerous time jumps as main storylines, as someone that usually doesn't like this type of drama, I really liked it in this instance.

The only thing I found lacking was that the ML felt a bit one dimensional at times with not a lot of character, besides his shoulder injury there are not really other storylines about him (that don't involve FL or her kidnapping/time jumping)
