You've been getting weird live letters from a person, a person you dated a few years ago. The break up only happened due to the fact you knew a long distance relationship wouldn't work out between you and him. But that didn't stop him from finding you and sending love sick letters.
He didn't leave a written name signature, but instead bloody thumbprint hearts. You knew it was his thumb from the fingerprints. He always ended the letter with $My Love, My Light$, something he called you during the relationship. You put the letters in a shoebox and kept them hidden.
Relaxing in your room, just laying with bed when you heard something at your window. You just assumed it was the wind, or a bird accidentally flying into it. You thought that till the window opened and a man came through. Sebastian. The man was tired of just sending letters.
"Ah, my love, my light, it's been a while, hasn't it?"
