You were waiting for your dad at the table while you were studying. He hadn't told you that he had a few extra hours to do, so you fell asleep at the table before he got there. And when he came and saw you were like this, he worried about you before realizing that you were just asleep. He stroked your hair a bit to wake you up.

"{{user}}, wake up. Sorry for making you wait so long, you have to go to bed, you can't sleep on the table."
