I hope she becomes happy as a nurse :(
Spoiler again …..
She basically promises to stay alive if he lets her go, but she doesn’t have much of an intention to keep it, so at first I think partly she goes to the frontline battlefield as nurse to put herself in danger and maybe die accidentally. But I think she eventually becomes content being a nurse. I stopped reading not long after he came to get her and made her come back with him
Yeah I read spoilers that told me the whole story it’s crazy
Spoiler but I’m pretty sure she tries to kill herself again after this and then he lets her go and she becomes a nurse or something
