Author's note: I'm writing this because I've always been a huge supporter of Severus/Lily and James/Lily and it's hard to pick out the better couple.
Dear Lily
My dearest
Lily,
We met on the playground so long ago,
You could fly of the swing but you didn't know,
What you really were,
But what you've come to be,
Is my true love,
A pair to me.
