Alright...First of all, who would you choose?
The asshole who made you his slave and is just generally a horrible person, the asshole who tried to rape you for revenge but, just for the record, it was a total misunderstanding and he's sorry, or the really nice and caring guy..... who just so happens to be your (NOT REALLY) brother.

Hatsumi made the wrong choice. She chose to stay in this situation.
(Btw, spoilers.)
Maybe it's a cultural difference... I mean, I get that women are generally not as respected as men, especially in Japan. But the main character of this manga is a total pushover. How did she fall for Ryoki in the first place? She admitted (even when she was supposedly in love with him) that she was afraid of him. But she never stands up for herself or fights back... she just lets everyone treat her like shit.

And the whole deal with her brother being in love with her, that is such a cop out in so many series. They're not REALLY related. So it's okay! But no. It is not. She grew up believing he was her brother, so he will remain her brother. If your brother confessed his love to you what would you do? YOU'D BE CREEPED-THE FUCK- OUT.

In all honesty, there was a part of me that ate this shit up. I wouldn't have finished it if I totally hated it. I wanted Ryoki to change or Hatsumi to grow some balls and punch him in the face. But in the end, neither or those things happened. Ryoki is still a disrespectful asshole, Hatsumi is still a dumb bitch and everyone is ok with that. Even her now celibate brother. I mean, really? Wtf.

I don't have much to say about Azusa... he has issues that he projects on to other people... and he's an asshole.

Hot Gimmick.... you're what makes me say "What the fuck, Japan?" (Along with many other, much worse, things)
