Miraculous and the broken girl

Ladybug and Cat Noir have been working together for the last 5 soon 6 years, Marinette has yet to tell her feelings to Adrien while he still want's to know who Ladybug is under the mask to try and date her without there masks or outfits on.

One day a new girl comes to there class, Jasmine Lessard a famous model who is also a singer and a dancer, she is serious but nice and fun with the others making Mari always happy for her childhood friend as they have fun together (Yup, doing that to Mari's past), Chloe is angered as Adrien tries to talk to the new girl.

Then a new hero appears, a girl named Loup Heart making them wonder why she keeps telling them that there parents might not be what they seem.
Who is she? Why is she like this about there parents? Why is Jasmine closed up on certain things about herself and Will Adrien fall for this new hero or Jasmine?
