Crazy for my best friend's dad

Everyone falls in love right?
But for me, it's impossible.
Well let me tell you, I'm crazy for my bestfriend's dad!
And I'm sure she wouldn't like it when she finds out.
That's why, I need to hide my feelings for him and never tell him how I really feel.

Renesmee Anderson, is a 17 year old girl and in love with Maxwell Callaghan, her bestfriend's dad.
She doesn't want to lose her bestfriend so she doesn't tell Max about her feelings for him.

But what happens when it's the other way around?
What happens when Max is the one, who tells her how he feels about her?
Will Melanie Callaghan accept their relationship? Or will she try and break them?
