I haven't watched the original: but I was really impressed with the storyline. I've seen an oodle amount of shows in general that have plot twists that spiral out of control and it's just nonsense, but not this one. yay!

I was scared it would happen in this show because it has multiple layers of complexity, but the story is handled with precision!
midway, two episodes were veryyyyy confusing because they were not revealling everything, but it all "makes sense" by ep 8.

IT IS A GOOD STORY! for those who like mysteries and twist hard to guess.

someone in the comments said it's not Kdrama but Ktrauma, and I can't agree more. the story is very heavy. it has a lot of existential questions and self esteem, courage, loss, death and grief. But the story wraps itself in a way that tries to answer most of these current issues in high school and life in general.

For the actors, I really thought there were two different actors from the past 1998 and the present. I was also extremely impressed an in awe in the execution of the minjoo- jun-hee dichotomy. we could feel the essence of each character even if it was played by the same person.

This show left me with an inspiring feeling overall in the end and it made me reminisce about my high-school years, about my own hopes and confidence.

I did wish there was something more after the final scene and more about this time travel system, but if we analyze all that it was, all the clues were in the show.

Clever plot, awesome actors, memorable story about a connection between two people.
