A lighthearted romance sci-fi genre turns to a very complex and deep storyline. The story started from 2 different timelines colliding with each other when the male lead tries to get the best version of the future by slightly changing his past.

You get the best of both worlds of 2 different types of romance, the very innocent and charming coming of age story and a more mature adulthood type of story. It is far from your typical cliches plots, the romance is naturally adorable, and the male lead is not your everyday obnoxious character. It's a fun drama in the beginning, but it will get on your feels as it starts to bring more depth to the story. Other side characters also bring warmth and have an impact on the main story. You can tell it's a great show by watching the first few episodes.

The concept of this drama is an amazing idea, the story, the scriptwriting, the acting, the chemistry, most of it was excellent, but there is a lot of back and forth between the 2 timelines that it feels like ur watching two different shows at once. It gets pretty confusing throughout the middle of the show. The writer still did a pretty good job "explaining" how the logic works tho, so it's easy to make sense of it.

Overall, it's still a good watch. I had a great time guessing the unexpected plots. The two leading actors were amazing convincing us to be the age of 18 and 31 at once. I'm glad to find 2 new actors I'm not really familiar with. Would I recommend this to others? Yes.
