Honestly the "aaaaaaangst" "Drama" and "What the fuck am I reading" tags would not be out of line for this chapter.
The way I read it, the blame is 10/90. Magical girl should not be projecting onto evil general, but she might not even know she's doing it. And more to the point, Former General basically just lured the magical girl into a romantic setup just to rip out her heart and step on it.
Here's the thing: The worst thing that can happen is not being told no, or the other party being disgusted. Because the opposite of love is not hate, it's disinterest. Magical girl is clearly pushing herself really hard to be able to do this, and Evil General cuts her off, rejects not her feelings but the validity of the feelings, and then proceeds to mockingly tear into her for allegedly using the general as a replacement.
That's not just a rejection, it's psychological warfare.
Her response was definitely brutal, but I don't think you're interpretation of it is quite correct, because Juuna isn't disinterested or fully rejecting her. She's completely rejecting the premise (and hurting Hane quite a bit in the process), but she's also saying that she wants to continue standing in for that girl, if Hane will let her.
Honestly, I suspect an actual rejection or betrayal would have been less painful.
On another note, I still don't buy that Junna ISN'T the magical girl that saved Hane. I think she just doesn't remember. We know she doesn't seem to remember her life before she joined the bad guys.
personally, i think theres almost no way shes the magical girl
between the confusing age stuff (even junna called her “older”), and the fact that junna was referring to her as a seperate person, almost like she was someone else that she knew of, i dont really think they could still be the same.
i mean, junna obviously wouldnt know that they were the same if she was in fact the magical girl, but i still dont think it makes since anymore
Eh. If we're assuming brainwashing/memory loss is involved, then it's perfectly possible for Juuna to be aware of her former self while also not realizing they're the same person. With that said, you're probably correct about that not actually being the case.
