Sweet Child O'Mine- Guns'n Roses

It is after he sees little Rosie in the arms of a tearful –but joyous, so joyous- Hermione, that he understands that he wants to have kids. One, or two. Yes, definitely two. A boy and a girl.

Draco, that waits for him outside the recent-mother Hermione's room, knows exactly what he's thinking as soon as he sees him. His lips quirk a little, forming the smallest of smiles, and gives him a fast and chaste kiss (After all, the last time Ron found them in a sort of romantic moment, he just couldn't repress his urge to puke).

And Harry understands, then, that they both want the same thing.
