What from these 3 should be my new Фан fiction? I need help, :)

So I have 3 ideas for a new Фан fiction I'm going to start Письмо since I'm ending Chair "Love Story" Далее week.

1*- Blair Waldorf always had control over her live, she decided what to do, when to do it and who to it with. She had the perfect fiancé (Nate), the dream wedding planned and all of Manhattan would be there on the happiest день of her life. But what happens when it all comes crashing down? What happens when she meets the man who is destined to change her life forever? (C/B).


2*-Charles бас, бас-гитара is known for his womanizing ways and boozing habit, and he does it all in front of his long time fiancé Serena VdW. Blair Waldorf is a free lancer who is hired to produce a plot to break their engagement off. But what happens when she ends up falling in Любовь with her boss? (C/B, C/S)


3*-Charles Bass, 20 years old and heir of бас, бас-гитара Industries. Blair Waldorf 17 years old and daughter of socialite Eleanor Waldorf. What happens when a teenage girl is infatuated with a married 20 год old entrepreneur who happens to be her cousin’s husband… Will he resist?


I'm going to write them all, but now I just need one... Please tell me your opinion. x)
