Sakumo eyed his cub dubiously, inspecting the mess over the counter and sniffing - it still smelled like sugar and chocolate; not things Kakashi was prone to getting into, generally.

"What are you doing, cub?" Sakumo asked, stepping fully into the kitchen.

"Practising!" Kakashi said seriously, attention riveted on the measuring cup he was holding. "Minato-nii's birthday is in two days and he told Mama he'd never had a birthday cake and he likes cake so he should have one." he said firmly, and Sakumo bit his lip, amusement and fondness mingling in his chest . . . with a trace of anger for those who had supposedly been responsible for their little nikkou before he quietly adopted himself into their family.
