Two six-year-olds would meet in their neighborhood's park everyday and play "House." Ciel was always Father. Sebastian was always Mother.
Father did business at the sandbox— he claimed a six-year-old's dream job, declaring himself the head of a toy and candy company that doubled as a spy agency. At home, Mother cooked and cleaned, brushing tanbark dust off the play structure. Then Father came home, and Mother laid before him a massive and entirely imaginary feast, where every dish had a fancy French name neither could actually pronounce.
One time, Sebastian's parents saw Father kissing Mother goodbye before he left for the office.
Immediately, their fiery anger brought House crumbling down.
