I love fantasy/ Sci-fi/ Time travel dramas. Right from the beginning I got this feeling that when it comes to fantasy dramas, Korean dramas always excels. This story was interesting bcz it involved time travel to save his saviour. But, by the end we see that the whole point of the story was only to deal with his past trauma and guilty feeling. Honestly, I don't like this concept. I don't think that knowing that the person we loved and who loved us, willingly sacrificed their life for us would be less painful. Even though they want us to live a good life, and even if we try to do so, the pain will never fade. Thank god it has an open ending. It's kinda confusing how again after more 15 years Ji woo still looks the same. I mean is he the 25 years old self after 15 more years or is he 40 years now? Idk. Anyways, I hope we have a season 2 where they'll be more clever and find a way to save themselves rather than willingly sacrificing themselves.
I don't like sad ending dramas. I mean it's an open ending but still I feel like the story was insufficient. There should've been more to it. So will not prefer to re-watch.
Acting of both MLs were fine. However, it was like he still behaved like a kid with him though he was a grown up man now. I was fine with it though.
