Along with the m pad manga, the story somehow ended up having more actual plot and character development than one would expect.
It will be difficult for Manaka: she KNOWS she wants a new life and stay away from that twisted mix of love and pain, yet she has been tamed to a point where it is part of her instinct, and lust is not something you can control easily. As a victim she can be pretty vulnerable.
I am interested to see how this goes: will Manka be unable to resist? Maybe Ueno will let her know what he has been going through and the two can try to help each other out of the mess. Maybe we can explore an angle where the two of them may not be sexually compatible due to their past and how they try to deal with it?
It might end up being Manaka being the one who is able to move on, but Ueno is still stuck since he is still close to Chisaki & co.
