I considered writing a well thought out review for like a total of five minutes, but I can't. So, allow me to just yap.

This drama had very quickly made it obvious to me that it would become my all time favourite. There are so many core reasons as to why, I'm not sure how to list them all. First off, the casting was splendid. I wouldn't change a single thing. The acting was impeccable. The emotions were so real. I adored that this drama started out with a focus on high school life, giving me that cute high school romance that I love so much. The fantasy undertones were the root, yet they did not take away from the sweetness of their youth. There were so many times when I genuinely forgot that this was a story of Im Sol going back and forth. It feels like she lived so many lives and we got to witness so much of it. I am also so glad that it wasn't a situation in which Sun jae's feelings were hidden for an unnecessary amount of time. You know how sometimes it'll be that the female lead likes the male lead and then you find out later that he liked her all along, but they tell you rather than showing you? I loved that this drama showed us his perspective so early on. There may have been some back and forth with him and Im Sol about their feelings, but we knew. However, I believe the miscommunication was just the right amount. It wasn't like they were going crazy trying to hide their feelings... Even in the last few episodes as Im Sol tried to stay away, it was obvious that Sun jae was just ignoring her completely because he could see through her efforts.

I loved seeing their youth, it just gave me butterflies the whole time. I'm glad we spent time in the past, seeing them all build bonds and grow together. Everyone's story was touched on well, we got see how In Hyuk, Tae sung, Sun jae, and Im Sol had come together as well.

Tae Sung became a very beloved character and somehow one of the most sensible of them all. I appreciate how his intellect was something present even in his youth and he learned how to better channel it as he grew older.

Sun Jae was just a green flag all around. I have so much to say but my mind can't pinpoint a single thing. He was great.

All in all, this drama really touched my heart. It truly was about making sacrifices and learning to sometimes be selfish and give yourself a happy ending. I think the saddest part was knowing that even though Sun Jae and Im Sol have their memories, those experiences that all the characters shared in the past are no longer part of their timeline. It's unfortunate to know that in some ways, they missed out on a very pretty life filled with sweet moments. That's why episode 13 was definitely the saddest for me.

Anyways, this was a 10/10 kdrama with amazing romance, beautiful moments of the past, and really makes you appreciate the privilege of time.
