(I copy pasted this from my own review comment on mangago) Even though its mostly set in school and has drama and potential for romance, its not too sappy or happy-go-lucky. This manga is angsty yet mature, with good doses of comedy. The art is beautiful and the artist and writer are really good at creating atmosphere and tension without it being too moody, its just right for a drama(?) like this. Also it's not atmosphere and tension 24/7, there's a lot of relatable moments and lighthearted moments. The balance of subgenres (romance, psychological) is really good and doesn't overwhelm the main drama genreof it. The pacing is also fantastic, but the manga isn't done yet.
And yes, there are psychological undertones, they start showing up in the middle and later chapters with a certain character fueling it.
The characters are likeable and relatable but all have flaws that help fuel the story when combined with their own different unexplained abilities. They're all well developed and complex.

In the comments of another manga site, a lot of people were saying they were confused by this manga. That's because you're supposed to try to figure out what's really going on by yourself, as the reader. So be ready to question what's going on and how the characters really feel/why they act the ways they do.
Anyways, this manga is SO good so far. I'm DYING for more chapters to come out...
