He's your best friend's father and that means he's forbidden for you..

You've always had a huge crush on your best friend's father even though you knew it was something that could never happen and that he saw you like he's daughter

You're younger and he shouldn't fuel in your desire, but he can't help it too

He came to look for his daughter but she wasn't there.

You're home alone

"Uhh..I guess I should leave then" he said with a small smile, but still standing there not moving
