If you're into time travel, this was a solid show that offers exactly that concept. Personally, I found the constant back and forth and calling every night over the phone redundant and confusing at times since I have to remember what that character did in that timeline, but the production team does a great job in contrasting the colors and also including the date on the side of the screen for us.

The pace is super slow for the first 10 eps. Yes, 10 eps too many. There was too many unnecessary slowww scenes and back and forth. A lot of the drama could have been avoided if they were smart about certain things, and while you may tell me "but that's why this drama exist!", I will tell you I have seen dramas where the plot is just solid and doesn't have me annoyed at all these plot holes! How hard is it to straight up just say what you want to say on the phone instead of saying "There is one thing I must do. I have something to say." You have one minute on the phone and you really want to drag it. Now imagine this happening for 10 episodes.

The mom was the most aggravating character due to her constant running away to protect her daughter bs, and the female lead wasn't the smartest. Good thing the mom and daughter both redeem themselves towards the end. Once it reaches episode 11, everything starts pacing really well. I particularly enjoyed the action! It got me making frowns and on the edge of my seat without even knowing it.

The cast is phenomenal, and I would like to give a shoutout to the side villain who be doing the most and the girl best friend. Her expressions and crying felt so real! The mom's acting was phenomenal too.
