This review is going to be pretty concise so you don't have to read much.
Quick Overview: Story is based around a bullied girl who is the daughter of the man who used to bully her teacher. As is common with these types of stories 75% of characters introduced are generally manipulative pyscho- or socio-paths, which can be interesting to an extent.
Story 6/10: Overall not really intuitive, the plot points are introduced rather plainly and predictably. Meaning, with a little bit of thought it's easy to see where the story is going. However, I do give props for decent pacing, which is something becoming much harder to find.
Art 7/10: The expressions are really well done, but the art overall is nothing special.
Character 6/10: As of this moment, outside of the Bullied Teacher, not a single character has anything unique or interesting about them. It's just a generic "Bully gets mad at girl for something stupid".
Enjoyment 8/10: What can I say, I'm a fan of this type of work. Psychological works like this generally can please me extremely easy with a decent plot introduced in a cool manner. Artwork is cool, characters are good enough, story isn't bad, is a good time waster.
Overall 7/10: If you want a good time waster that you can read without thinking then you can give this manga a try. However, if you're expecting a plot you can dive into with interesting and thought-out characters working their way through a complex plot, you're probably better off looking for another manga.
