In an alternate universe maybe Draco had to go and leave Hermione. This is what could have happened, how he felt. Maybe he thought he wasn't good enough for her so he wanted to better himself but he's hoping she'll wait for him.
I didn't mean it when I said I hated you.
I didn't mean it when I said you should leave.
What I meant is I love you,
But I had to let you go.
You'd never be truly happy with me,
And that I had to swallow.
I wanted to be selfish.
I wanted you to stay.
But darling I'm just hoping,
We'll find each other some day.
