I came in expecting a story that's similar to It's Okay, That's Love due to the summary but It's Okay to Be Not Okay turned out to be a different drama since it has this mystery thriller vibe to it.

These are the reasons why I enjoyed this smart and creative drama to bits:

1. The drama makes use of the main settings to enrich the story that it was about to tell.
2. The cinematography and the editing of this drama is one of the BEST I have seen due to its creativity that made me laugh a lot and has more purposes other than for aesthetic purposes.
3. The animations are not overdone and the editing team has somehow found a way to make them organic.
4. The character development of this drama doesn't feel rushed and you'll find rooting yourself rooting for the main characters and it's satisfying to see the way their character arcs are concluded.
5. The individual stories of the patients have actually impacted the main story with their interaction with the main characters. Not only that, but they were also nicely tied in the end.
6. The dialogues are written in such a way that it alludes to the main characters without exactly specifying the names of the main characters.
7. It was interesting to see how they make use of different literary works as their episode headers. This was one of the few dramas that I actually paid attention to the title of the episode.
8. OSTs and background music are really good.

In regards to the acting and casting, this drama really did well and I won't comment anymore about the casts' acting since I was really satisfied.

Overall, this drama brought a lot of nostalgia due to its use of literary works that I've read when I was young and was glad that I was coerced to watch this drama. This drama will have a special place in my heart since it is one of the few dramas that me and my siblings watched at the same time.
