Yume was quite disgusted by the idea of having anything to do with Miyuki's happiness. As far as she was concerned, his happiness and her had nothing to do with each other and she didn't want them entwining at all. Of course, that could have just been the spite talking, or it could have been her continued digust at the type of manipulation she saw him as being capable of. Whichever the case was, it was at least a little comforting, that Karma in this world seemed to be so proactive. "I guess it's good that karma isn't just something people talk about to make themselves feel better," she stated. She knew in the world she'd come from people spoke of karma as a form of justice but knew that more often than not, some wrongs would never see true consequences. At least, she could rest easy knowing that if he remained as he was, he'd pay for it...
Speaking of recompense, there was apparently the matter of the lad's returned memories. For all Yume knew, returning his mind to him with the memories of her own debauchery might break him in some way. And Mugen's words on the matter implied that it was possible that could happen, but this wasn't the sort of thing that could be mediated ahead of time. Mugen's lesson in this form was that if it didn't make you better it would make you lesser. This was considered a bonus to her previous lessons and she supposed if she applied the logic of her earlier situations to this, she could say that attaching herself to Miyuki permanently would have made her incapable of reaching even her current height, making her lesser in the grand scheme of things. "Sou ka, so it one of those free will choices," she said seeming to understand the whole of the situation in theory. So what did she think? Well, a kid's cartoon movie had once mentioned either running from an experience or learning from it, given the profound impact of such a statement, she didn't think it a good thing to do for either of them to stand in the way of the lad learning his lesson. If he collapsed it would be no one's fault but his own, if he learned from it, maybe he could live a happy life without ever darkening her doorstep again. If she was being fair, the latter was in general what she wanted for most people after they'd done their due diligence. "After some consideration, he should definitely get his memories back. I won't stand in the way of someone else's learning opportunity. Even if the lesson is particularly tough," she concluded with a light giggle. "Alright, I guess I am watching someone's mind roll a d20 today~" she stated, wondering if that might have been giving the lad a bit too much credit.
