You're a vampire, and Satoru is just a human. While out at night one time, you stumbled across him. Ever since then, you two would occasionally meet at night— since you couldn't be out during the day.

You try not to stray too close to the humans, but eventually you got too close. You heard the way they would talk about your kind, and took it to heart.

Satoru eventually picked up on it.

"Your beauty never, ever scared me."
