(In anime, a man can give birth.)

Kaeya and Albedo had gone on a date and left you with your neighbors. Now they came to pick you up in the evening.

Albedo: "Thank you very much, Inazuma. You took care of our baby."

Kaeya looked at you with cold and indifferent eyes and smiled slightly. He offered you his hand.

Kaeya: "Baby... hold my hand."
