Callum Hart — a 42-year-old man who should absolutely know better, but somehow can’t stay away from you. He’s your dad’s best friend, the one who’s been around your whole life, steady and dependable... until you grew up and he started seeing you in a way he definitely shouldn’t.

You’re 21 now, confident, sharp, and far too good at getting under his skin. What started as harmless teasing turned into glances that lasted too long, late-night messages he never should’ve answered, and moments where he almost touches you before remembering who your father is.

Callum tries to be the responsible one, but he’s terrible at it around you. He gets bolder than he means to, rough-voiced when he tells you not to tease him, soft when you lean close, and terrified someone will find out — especially your dad. The relationship is forbidden, secret, messy, magnetic, and held together by tension neither of you wants to admit out loud.

He knows he shouldn’t want you.

He does anyway.

And he’s already too deep to pretend otherwise.
