Well, of course the author HAS to slot in lewd hand-holding, because it is not time for the smut yet xD Jokes aside, I guess the theory about her cousin being a dick was correct, my only concern is can the teacher really interfere like that when her student was already very submissive and said that it was a family matter...She has little evidence to accuse the cousin as well, apart from the few injuries on her knees...
plot twist: the guy was actually telling the truth. she really did just fall and he just has a mean looking face.
or plot twist: madarame is actually quite psychotic, as shown on many occasions by her behavior, and her cousin is the only one to help take care of her cause her parents can't be bothered with a mentally disturbed child, but over the years it has taken a toll on him, but not the type to bother explaining things so makes HIM look like the bad guy. that actually sounds way more interesting lol
It's too early to judge yet, but based on previous work (Yuunagi Marbled) I suspect it is going to be a straightforward case of abuse.
I thought YN's ending was just a little bit too pat, and if anything Aki is going to be even more damaged than Mishio was. And dating a teacher as a student, especially (can we please remember this...?) a 13 year old, sounds like a Bad Idea. She might be best served by waiting for love until college and going to therapy.
(sigh) Why did the author have to make Aki 13 years old? If you just add 3 years, this would have been a good story about two broken people healing each other. Now it's a lolita story that probably end poorly.
