This is the first drama that I've watched after reading the original source material (in this case, a webtoon), so this will be a review where I inevitably compare some elements, but I'm still trying to be as objective as possible.

I really loved the webtoon — the plot, the lack of cliches, the straightforward female lead — and was really excited for the drama. But from the start the spark was missing for me. It felt pretty well written but the development of the leads felt jumpy and I'm not sure the chemistry between the actors is all there.

Plot-wise, this was really a drama that needed a full 16 episodes because of how much plot there was. There's the 18th life backstory and Jieum's 1st life backstory, and I really feel like they glossed over the car accident (18th) just to make time for the other plot. The plot that seemed to kickstart everything felt very unimportant by the end.

Now, the biggest issue I have with this drama is the backstory behind the first life and all the changes they made to it. Just in general, the backstory of the first life felt lackluster, but if I hadn't read the webtoon prior to watching this might've been something I could forgive, but knowing what I know, I find myself realizing just how MUCH the overall message was changed. Whereas the webtoon seemed to give Jieum a lot of agency in choosing who could be part of her life and going against "destiny," the drama created a lot of rules to take that away. There were consequences from the universe telling her those decisions were wrong, and even more so, the fact that EVERYONE was incorporated into her first life (vs. the coincidental one in the webtoon) seemed to underline that fate does exist, and that people with so-called intertwined destinies would meet each other anyways. Being anti-destiny was one of the things I loved about the webtoon and I felt like the drama completely undid that.

Next, my other big issue is the ending. Anyone who knows me knows that I hate the amnesia trope, especially when used at the end, and this was the perfect example of why. It just leaves SO many plot holes because she lost memories of specific people instead of just her past lives — why wouldn't she question her life changes and memory gaps? How did she get her job back? What about where she was living? Wouldn't other people talk to her about the people she'd forgotten? The only direction I can see the story going is Jieum starting to second guess herself and the people who randomly started to insert themselves in her lives. But obviously, there were no more episodes. The story just...ended.

Overall, I actually think this had a promising start. The cinematography was gorgeous, and there is so much good material. Even if I wasn't immediately convinced, I was glad I gave this a chance and I did see a few scenes that I liked, some familial bonds that touched me. By the ending however, the backstory had become so messy, the philosophy had become unclear, and the romance had fizzled out. I'd lost all emotional investment in the story.
