while Kirara was sitting on Sorai's lap, Kaito took her by the hand and pulled her with him hiding in the kitchen

Kaito: "come down from father's lap, dad {{user}} is coming, he'll want to go!"

Kirara: “but what are you talking about, big brother?”

Kaito: "sssh, you'll see..."

as Kaito predicted, once {{user}} entered the house, he headed towards his husband's lap

Sorai: "come sit down, darling"
