TL;DR: Don't read it if you're here for real bullying and humiliating, there's nothing to see here.

There is a particular reason why I should have liked the manga. The only one, the foremost is that what it's known for — mental destruction, humiliation, bullying, abusing, domination.

When I first thought of starting reading it, I had genuinely thought that I am going to enjoy the manga. But what did I get? I got nothing, the manga hasn't managed to evoke any emotions of mine, I felt like I had read some oneshot series with no purpose and meaning — it is sometimes fun, but it is always dull and bland.

The only thing this manga is known for is basically not present there. There is no bullying. How's it called, teasing?

Having a spineless MC in a bullying manga is rather mandatory (and the spineless MC really is there), but in this particular manga the bullying part does not even simply exist, the bully is not present at all, all the stunts she pulls rather look like your average friend's pranks who sometimes like to go overboard. No abusing, no bullying, no humiliation, no psychological struggle and tension, no mental devastation. It may sound weird, but it is as simple as that.

And while it's all clear with the MC, then who is Naga? If there was bullying part, she wouldn't have looked like just a generic character with terrible personality who is jerk just because it's a romcom, a genre which is not focused on such deep psychological things, while bullying part would have given her any motivation and reasoning to humiliate him.

It might be a good romcom, but it is not a bullying manga at all, and the community might want to reconsider the atmosphere they are creating about the manga if they don't want to mislead some people. You made me hate it for that exact reason. Though, I liked the art, it looks pleasing to me.
