I like the fresh take on some classic ideas, if pulled off well it could work really nicely. Only reason I'm commenting is to say that there are certain readers who won't let the following fly (because it's been done to death, and badly, and because it can be (emphasis on can be, I'm not implying this is your intention) an example of misogyny etc in writing): "A girl... is in love with him since he saved her life". I'm sure there's more to that, but be careful with this one. Hope this helps, and good luck with your writing!
