Does this have a novel? If so, can someone spoil me on how she gets her body back?

The novel exists, someone posted the link in the comments, but seeing how no one is able to tell when the mc will get her body back, i'm assuming there's still a long way to go :(

Major Spoiler:



















I've read a comment somewhere here that the mc as a bird will accidentally drink a poison then she'll go back as a person, vice versa.
