I generally recommend this drama, especially to those that have read the manga or watched the anime. If you haven't, I would say it can feel there are some plotholes or rushed parts here and there but it's a good adaptation. If you have read the manga or watched the anime it's a lot easier to fill in the bits missing but also as it tends to happen, this isn't better than the manga because of that same reason.

I came to this drama with low expectations because adaptations tend to be not that good and very rushed, something that clearly happened with the movie version of this same title (because obviously it was impossible to fill the plot of 30 volumes of manga in a 2h film). It was difficult to not make comparisons because despite overall thinking this series is so much better than the movie simply for having most of the plot points of the original work, I also thought that some of the characters were better portrayed in the movie, namely the protagonist. As another review has pointed out, the main character here lacks the uniqueness and creepiness that the manga character is supposed to have. I feel the movie did a better job at this. Sara Minami is pretty by society standards and they didn't try much with the hair or her behaviour and demeanour to look closer to how she's supposed to be, she just comes across as a bit shy.
Also, while I think Rinka Kumada did generally a good job as Yano, I felt she was missing the subtext, in the manga and anime there were always instances where you could tell she knew what was going on, and would work things out before anyone else and she was mature for her age, I don't think this was portrayed very well in this series and I missed those nuances of her character. I also think physically I expected her to look more like a gyaru, more similar to how they did in the movie, that it's how I imagined her in the manga. Also one of the things I precisely liked of the portrayal of Yano was the fact she's fashionable and more adult like but she also has good grades and cares about her studies, what I think it's not a very common portrayal in mangas for someone looking like a gyaru (and smoking!). In this series to me if I wasn't told through the part of the rumours I would think she's just an average high schooler. Maybe they didn't want to portray her as a gyaru to keep up with the times, but they could have done something else to show the contrasts of her character since there is nothing in the way she acts or speaks here that tells me how she is either.
On the other hand, I was happy with the rest of portrayals, and in fact I was very pleasantly surprised by Riho Nakamura as Chizuru, I think they nailed it with her.
(If I'm being picky though I have mixed opinions about the portrayal of Kazehaya's father, it's a difficult one, but I don't think he looks serious and stern, just kind of awkward and forced? I don't know how to feel about him).

While I'm generally pleased with how much they fit in this show of the source material it could have been even better. Some bits felt a bit rushed, while some others, like some of the dialogues seemed a bit too slow. I enjoy slow and I enjoyed the slow pace of this drama in those dialogues, what I'm not so pleased with is this coming as a detriment of other plots or scenes being rushed. I generally would have preferred this drama had been between 15 and 20 episodes long, it would have given the time for everything. Another thing that also was a bit annoying for me it's how they cut out almost every single kiss or show of a more mature relationship that appeared in the manga/anime. I can imagine why, but many people watching this has read the manga or watched the anime, and many others that haven't and liked this will potentially check both or one of them, so why? I could tell even in scenes when that was being cut, and any show of affection between any of the characters was quite awkward in my opinion. The girls dynamics were on point though.
Acting was generally ok, but at times for me it was a bit off, sometimes it felt like they were reading the lines without emotion or like they were doing a theatre play instead of a recorded show. Maybe also like they were trying hard to use the same exaggerated expressions or body movements than in the anime? what could feel forced and cringey sometimes. I think this happens more in the first half of the show than in the second. I didn't hate it, but I didn't love it either.

Music was ok, some songs were cute, some gave me the vibes of the main theme of American Beauty? Overall it was ok, but I did notice a couple of times in the first few episodes a song would play in the background that didn't necessarily match too well with the vibe of the scene (for example, a scene with serious dialogue and a bit too happy song in the background).

I can't see myself rewatching this, it was entertaining, watchable, cute at moments, loved the scenery and atmosphere but I prefer the intensity and the emotional portrayal of the manga/anime so I'll gravitate towards those before this one. But as I mentioned before, as an adaptation I'm pleased and it's probably one of the best manga adaptations of this genre I've seen despite its few flaws.
