Kuroko hadn’t even meant to be out that night. Even with as much personal control as he had it was always a risk allowing himself to be completely surrounded by humans on such a powerfully magic night. But there he was and so was she, dressed in a black corset and purple tulle skirt, her pointed hat completing the look; a classic witch.
He knew instantly she was human; her scent gave that much away. But that didn’t stop him from being intrigued, more curious about her than anyone else at the party.
A glass of punch later and they were talking. She was charming, a beautiful smile almost always present on her face. In all his years of existence, he’d never meant anyone like her before.
It hadn’t taken long for him to fall for her completely.
Explaining to her his origin and species had been nerve wracking, but she’d taken everything in stride, understanding his needs and even coming up with very viable alternatives to his drinking from humans.
And now, here they are, a year later dwelling in his castle on the hill. But he knows, better than most, passing time is their enemy. While he remains ever young, she continues to age. It isn’t a problem, per se, but Kuroko knows his unbeating heart; were she to cease to exist, it would be the literal nail in his coffin.
Her eyes are soft, hand gentle against his face as the smile he fell in love with takes over her face. “I’m yours, Tetsuya. I trust you.”
He sighs, drawing her into his arms, body shaking. He never thought he’d see the day he wanted to change someone, to take away the sun, the warmth, the light.
As if she can hear his thoughts, she whispers in his ear, “In case you hadn’t noticed, I’ve always preferred the shadows.”
He smiles around his fangs, pressing their points to her skin. “Are you sure?” he asks one last time.
When she nods, he bites down, releasing the toxin that will transform her, make her one of his kind.
Make her his forever.
