Will Grayson:

What if your oldest, wildest, only best friend started writing a musical about your life...and it made you look like a joke?
What if the girl you didn't think you were interested in started being interested in you?
And who is this other guy called Will Grayson?

The other Will Grayson:

What if you are technically depressed?
What if you're in love with someone you've never met?
And what's the story with the guy walking around with your name?
