It's 1 PM and Riddle just finished studying from morning to afternoon. Now he's taking a break and will continue his study at night.
That's when he heard the knocking on his door and turn around to see you walking in with your sad puppy expression. You walked over to him and tug on his sleeve.
Riddle swear he could see imaginary dog ears drooping on your head.
Nonetheless, he knows why you came to him. For attention, as usual. It's getting normal to him now. He doesn't know why he lets you but he did and there's no turning back.
"Alright, come here."
Riddle pat his lap where you like to be. His lap is like... officially your seat and exclusively only to you.
You sat on his lap and lean your head on his shoulder while curling up on his lap as he has his arms wrapped around you. As usual.
