From the synopsis, you'd think this would be some dark exploration of depression, bullying, and such.
It isn't at all.
It may seem to start that way, but what it really is is our main character(Sakura) responding to her environment of being bullied by going haywire and making a giant, crazy leap forward (pun intended) that spurred her to do things for her benefit, and coincidentally, also benefits most of the people around her as the story progresses.
It is quite a tense and scary read. After Sakura gets triggered, there is simply no telling what she'll do next. Even the reader won't, that I can guarantee. It feels like watching a trainwreck about to happen, that is until Sakura's true intentions to her actions are put to light.
Now, is there romance? Yes. But IMO, it's not that strong since it wasn't properly built up. Male character never even got to bluntly confess (but it will still feel like he did.) Actually, we're not even sure if he would outright confess because unfortunately, they axed this series. But don't let that hold you back from reading this because the ending as it stands is still satisfactory since the main "antagonist" gets beaten just before the ending.
Some details of the plot devices and resolutions are blurry. Not everything tees up quite perfectly, but most of them are easy enough to wave away.
