...In the Giving (слэш)

Snape’s brow sinks low over his eyes. “Why.”
“Wh—?” Potter blinks twice then groans aloud. “What do you mean, ‘why?’” he says, snorting an incredulous laugh. “God’s sake, Snape, have you never got a gift before?”
Or,
Harry's been giving Snape gifts, each more thoughtful and precious than the last. It takes Snape 22,000 words to figure out why.
