So the heroine was originally, it seems, her own unique person - as we can see with her being friends with many people, girls included originally - but going back in time has made the heroine a isekai'd possessed person.
So I wonder what happened to the original heroine then? Is she in the isekai'd person's body back in our world, or what?
It always frustrates me a little attention is given to this detail with isekais, because it's just ripe for expanding up; particularly in a sort of body horror direction. You've been possessed and have everything taken from you, and no one even realises!
Imagine a comic where the brother of a heroine or villainess realises that they've been possessed, and acts in the background to find a way to exorcise them, all the while they watch as everyone fawns over the new version of their 'sibling' - or what if this isekai'd person ruins their siblings life, and they have to act before it's too late to save any remnant of their sibling's life, etc.
Anyway, no point in just spitballing ideas that aren't going to be used in these comics.
