I watched several Korean dramas that involved some type of time travel and this was one of them.

I couldn't decide what rating to give this after seeing the very last episode.

I love police dramas because of their chemistry but the chemistry in this one wasn't there. It was mainly about the main ML struggling with guilt in what he thought his father had committed. His goal was to make sure the victim whom he saw struggling to get along with life wouldn't get hurt anymore. Yep...it's about a girl...it always is.

I recognized the main ML from Psychopath's Diary. I really didn't care for him in that drama but I liked him in this one.

I just became somewhat disappointed by the last drama. I figured out who the main culprits were by the 5th episode and by the end it turned out that I was right. This was kind of disappointing because I was hoping I was wrong but I wasn't.

The origin of how the 'Train' came to be was never discussed. I wanted to know what it's purpose was. By the last episode to me, it just wasn't no point of why the 'Train' existed. It didn't have a proper ending for me. It just seemed that the way the people's lives were will always be in a loop.

It was a good watch but I kind of felt let down in the end.
