Little Lion and His Dragon

After the fight in the bathroom during HPATHBP, Draco and Harry are made to write to each other. They start flirting and gradually fall for each other. But not everyone is happy with the new couple.

Demons run when a good man goes to war.
Night will fall
And drown in sun
When a good man goes to war
Friendship dies
And true love lies
When a good man goes to war.
Demons run
But count the cost
The battle is won
But the child is lost..
