Summary: Just watch it and let it sink in because, in reality, it's complex and not overly melodramatic.
This series is intricate and tries to tell more than it can fully explain. You can enjoy watching it more than once because there are many symbols for you to decode. If you're a hardcore fan of series that delve into the philosophy of life, you'll love it and want to rewatch it, at least once more.
The romance part is just a way to lighten the heavy nature of the story and serves as a tool for the writer to tell the narrative. In the end, the series tries to take us on a journey to learn about the differences and the subtleties of life's transitions. I think the Male Lead (ML) performed excellently, living up to his reputation, while the Female Lead (FL) was standard. I didn't feel any disconnect in their performances.
I rate this series very highly because I don't see it as a romance series. If you're looking for a good romance series that will make you cry over a romantic relationship, there are definitely better ones out there. But if you're searching for a series that explores philosophical themes of life, this one will definitely be top of mind. It even gives off more of a J-Series vibe than a K-Series one.
