F for Fast food

It was another sunny morning in Kaiba household-

"Katsuya! I told you not to pack him that stuff!"

Katsuya winced. He had forgot that Seto was in early today for work. Seto's usually early, but today he had some meetings in afternoon so he can't catch up with work on time.

Therefore Seto got up at 6.

The reason why Katsuya got up at six is because it was his turn to make Kai breakfast and lunch. And he wanted to slightly cheat even if word 'cheating' does not exist in his vocabulary. He's just not in the mood to cook so early. So few fast sandwiches, some soda and snacks were planned.

That is, until Seto caught him packing that.

"They won't die if they once eat tasty stuff."

"Healthy food can be tasty as well," Seto argued, tossing his briefcase and jacket on the chair and basically stomping over to the counter.

"Oh really?"

"Yes. You just suck at cooking."

A pause.

"Well you suck at lot of things but that's beside the point," he smirked, watching Jou get furious red in face. From anger, of course.

"Father, I would rather not hear about your and dad's nightly endeavors." Kai, fifteen years old, jumped into the argument between the two, effectively shutting them up.

Now that red in Seto's and Katsuya's face was from embarrassment.

"Kai we weren't talking-"

"Yeah, yeah. Where's my food?" The kid wasn't buying it. He grabbed the bag with food and turned to leave the kitchen.

Seto stared.

"HEY! Get back here, smartass! You're not taking that food to school." Seto caught up and took the bag away, making Kai stare at him. While Seto proceeded to pack slightly healthier food, Katsuya sneaked over to Kai.

"Sorry, we tried," he mumbled silently to make sure Seto doesn't hear them.

Kai just sighed. "You just can't beat father, can you?"

Katsuya grinned and ruffled Kai's hair: "Nope."
