A very short review for Nagatoro. (Minor spoilers in the third paragraph)

I see tons of people either hating the series entirely (usually because they only read the first couple of chapters before deciding to puke) or loving the series like how I personally did.

First off, I'll say that the first few chapters are indeed very mean and set a horrible impression of the manga at the start, Nagatoro seems like every other bully that you might see in a movie about bullying. I almost felt like dropping the manga too till I read a few more chapters when I found the manga to be much more different than what it originally proposes to the reader.

The characters that I first found dislikable were later more and more likeable as you go. While the plot goes hardly anywhere and the characters barely grow, you definitely see the change.

Overall, what I would say is that the manga gets better as you read on.
