This was my first EVER Kdrama and Asian drama in general. It was the Kdrama that got me into Kdramas and later C/J/Tdramas. I watched this almost exactly a year ago (October 2020) whilst it was ongoing and ironiclly enough, it is the only non-romantic Asian drama I've watched and I only watch dramas with at least some romance.

I'm surprised no one talks about this drama and a lot of people don't even know about it. It is extremely underrated.

I watched this drama whilst it was on going and it had me anxiously anticipating the next episodes every week. It had me theorisng the ending from the very beginning and every episode had me shook. I still remember it very clearly. This drama had no romance, and would have been truly disturbing if it did. But, it had hints of it, hints that the FL may have liked the ML in a non platonic or familial way.

This is the ONLY time travel drama I've seen that actually looks at the science of time travel whilst timetraveling, and actually focuses on how timetravel came to exist. It is a very real world detective drama mixed with outright sci-fi, completely different genres that clashed in the best way possible. It also had me obsessing over time travel dramas for months.

My favourite part of this drama was the story of the ML's parents. I LOVED his parents and they had the most interesting as well as heartbreaking storyline, one we see at the very start of the drama. I would have been happy just to see a drama of their story. I wish we got to see more of the ML's dad, he was the most badass character in this drama and with the best character development, not to mention, handsome as hell.

The ONLY thing I HATED about this drama was the ending. After spending weeks theorising just about every ending I could think off, they somehow came up with the worst ending for this drama that I couldn't even contemplate. Considering how this drama focused a lot on the science of time travel, a science that made sense especially with the chronological order of events, they somehow made the ending make absolutely no sense whatsoever. The last episode made a 180 and completely deviated from the plotline of the previous 15 episodes.

I highly recomend this drama to anyone despite the ending, because the first 15 episodes are definitely worth the watch. It is still one of the most UNIQUE Kdrama's (and Asian drama) I've seen or heard of and the plot was very detailed and every episode was unexpected. You will not be able to anticipate what will happen the next episode, forget anticipating the ending. There are so many twists in this drama and I LOVED almost all of them.
