I have a theory, this might be right or not. So they have confirmed they like each other so Raon wouldn't sacrifice himself or go to the OG plot. So I think that the OG fl might be also got reincarnated(I mean there's a new one on that body) and read the OG novel. And she also likes Raon and planning to choose Raon but sorry for her Raon already like someone and won't even look at her properly so this girl messes everything up and in the end she will die in the hands of Raon.
Honestly, I don't think this would come true but well
Ps. I haven't read the novel(if this has one) so I am not giving any spoiler, this is purely my imagination
