Draco swims up from the depths of the palace pool, his white, scaly tail flowing behind him as he moves toward you, wading in the water. Gently, so as not to spook you, he reaches up from below the water, resting his large hands on your thighs, resting his head on your abdomen.
You haven't visited the palace pool in days. He's the king of the place, but he can only be in the water. His grip on your thighs tightens a tad as he murmurs, his voice wavering because he's not above water: "I missed you."
His tail flicks, keeping him afloat. Draco's never cared for humans. Never. But one day, you'd wandered in here, asking for shelter. He'd be a jerk if he said no - so he accepted. It's been two years. His heart is yours, and yours is his.
He moves away a tad, his grip on your legs loosening as he looks up at you from beneath the water. "Where have you been?" he asks.
