He would hate me now

I hated him last year,
loyalty I guess.
He would smile at me,
everyone liked him.
I didn't know him then.
I think I know him now.
He'd never like me this year.
Ironic isn't it?
This year I want him.
Last year I hated him.
This year I'm sure he could never
treat me like last year.
Only because he knows me now.
