The sexual harassment that people get away with in the world of hentai is really ridiculous. When the student in chapter 2 pulls his dick out in class and shoves it in the teachers face without any consequences... and then challenges the teacher right after for all to hear "if I ace my test tomorrow you have to have sex with me." Just too ridiculous...
One of the best manga's that needs a hentai adaptation that also follows the manga to the letter, this series needs a sequel as in part 3+ it's so good.
