the whole amnesia thing was useless, it would've been better if "amnesia midou" had gotten a little development, , yes shiho would be able to delete those pics and be safe right now, but I think scene right now is kinda boring
if "amnesia midou" got a little development, this would explain why mc would be hesitant to kill her, and if she fell in love with mc again, she could go yandere once more,
and then we can add this shiho in trouble scene, coz according to "amnesia midou" shiho is close to MC and she doesn't want that.
plus after torturing shiho, midou can find about mc's friends with benefits, or maybe her memory, all of it leave us right about where we are now.
