Man, I do really love this manga. At least what little of it we've gotten so far.
Anyways... speculation right? Some people think that Aki popping up so soon doesn't feel right. That it should be something reserved for a finale or further down the line at least and that, because of this, the bullet isn't going to work.
Personally? I think the bullet is gonna work, I also don't think Aki is anywhere near prepared for the realization that she's fallen in love (with cupid assistance) again.
I think it might she have a breakdown because of it and force a redux further the down the line. Suitably angsty I think.
