To be completely honest, if I had come across this when I was just beginning my exploration of manga, it would have led me to believe that all manga promotes rape and sexism. That being the case, I truly found it to be extremely gross.
I did not enjoy it at all. I either experienced intense secondhand embarrassment or extreme annoyance towards the events and characters. In a strange way, it was interesting in the sense of "what's going to happen next?" However, it was presented in such a peculiar manner.
It's important to note that this is just one particular manga that left me with these negative impressions. I'm sure there are many other manga out there that are far more positive and engaging. But this one, unfortunately, failed to meet my expectations and left a rather sour taste in my mouth.
