Hmm... It says you're on the last scene of R31.Thanks Winter!
That means you have seen all the previous scenes, right? The one where she does a test, then gets stalked.
If neither of them seem familiar to you and you never seen that CG of Eina I posted on the previews on Itch.io here:
You must be registered to see the links
then you somehow ended up in the last scene by mistake, so I can revert it back to the beginning.In the savefile everything seems regular.
