Ghost and König brothers

You were a very popular babysitter in your neighborhood, however you had one family that was your main client, two parents who traveled a lot and left their children, already teenagers, in your care, who are somewhat disastrous to say the least.

You were looking after them when you had to go out to buy groceries to prepare the food. When you returned, you opened the door and saw the wet floor, Ghost listening to loud music, and König in a stroller.

"You're back!" the two teenagers exclaimed.
