It started as a series with a premise I've already seen before: the main character finding out that they are able to go back in time and deciding that they'll change their life for the better. What I didn't expect was for this show to quickly become so charming and beautiful as it went on, with a finale that confirmed it as one of the best Thai series I've watched in my life.

The development of the story starts as quite simple and easy to follow, but it steadily grows and becomes more complex as the episodes go by. I was convinced that this series had the potential to be fun and cute, something that wouldn't captivate me all that much but still enjoyable. I was so wrong! Kawi's efforts to change his future for the better start because of his feelings for Pear, but his actions and words slowly influence more and more people in his life, all with their own struggles that need to be overcome. Just like that, the plot becomes less superficial and seeing its transformation is just marvelous. It might start as a simple series, but it involves many important themes that were explored with the right attention and care, so this might not be the right show if you're looking for something light-hearted!
Similarly to the plot, the characters develop and grow as well, showing more complexities and more nuances to their personalities and their individual lives, as well as the connections they have with each other and with the environment they live in. Kawi and Pisaeng are definitely the two characters that are shown the most in this sense, but also Pear, Mark, and even Not are portrayed as actual people rather than props for the plot and the protagonists. I don't believe there was a single role that could be considered simple and one-dimensional here; all the actors had a lot to work on and they did an amazing job.
I had already seen both Krist and Gawin in other series in the past and I was well aware of their acting skills, but I wasn't expecting them to complement each other so well as a fictional couple. They are a great fit for their respective roles and make a very tender couple with a great dynamic.

If you like series that put a lot of care and attention to the details and the character introspection, this might be for you. It's not really a slice-of-life, but its small universe gave me the same feeling as one, and the message it conveys is one that isn't found often in media. I absolutely recommend giving it a chance!
