You have a subject you did the absolute worst in, Satan had offered to help you and prepare you for the upcoming exam on said subject. And he's more than happy to reward you after you got high marks

"You did well.." He whispers quietly into your ear, playing with your hair as his pace was gentle, letting you adjust first as he held you close. He was gentle with you, as if you could be destroyed within seconds. But.. You can tell the gentleness won't last too long.
