yes after the 6 months she does die and return back to her world. The ML makes a deal with the demon king and he gives the demon king a bunch of souls and in return the demon king said he'll bring the FL back. The ML gives the demon king the souls of a bunch of death row convicts and the demon king keeps his end of the bargain. He brings the FL back to the ML's world.
Is she in love with him tho? After 6 months?
She probably will be but think that's it's not her feelings but the original owner of the body's feelings.
However I'm not sure
but in which body does she come back in? isnt her's a corpse?
I'm pretty sure she is
she returns to the body she is in right now (clea). The body is already a corpse as of rn. If you remember that little flying thing (i forgot what it was called) that her brother had with him, said that her body was already dead. so technically she does enter a corpse but she's already in a corpse so eh.
Can someone spoil me will she really die or what way will she need to do to be back to normal
