This seems like a good story, but the dialogue is crazy. When you want someone to say something.. here I'll give you an example.
"We used to go to school together, but she probably doesn't recognize me now, since I've changed a lot," Mixi replied.
You need to use " because it organizes your dialogue and makes it look better.
And in the first chapter when Drake introduces himself, you shouldn't say "Hi I'm Drake. A famous celebrity." It should be more like, "Sup. I'm Drake. You may know me from Degrassi or maybe you've heard one of my songs." Or something along those lines. Cause just bluntly saying I'm a famous celebrity, you're putting more detail into it and making it more interesting. Get what I'm saying?
I hope you don't think I'm being a bitch, because I'm really just trying to help. This story sounds promising and I just adore Drake. So keep updating!
Very interesting plot. I like this. Just work on the grammar sense and it'll be the best ever. I can even edit the grammar parts for you, if you need help. :)
