yeah I prefer your theory too LOL I just thought because of the scarring she was shown to have maybe she was actually sick or something. Im sure our little MC wouldn't have understood if she was dying and preparing her for the future. Maybe she knew she'd be stuck somewhere in a spiritual sense(?) Or sent back if shes a transmigrator then that would work too? ( ̄∇ ̄")

My theory is that Ruri is the transmigrator she taught Bunny weird expressions and at one point mentioned her being a “villainess”!! Prophecy notebook is just all the things she knows about the novel she read.
