Hades and persephone only had like one daughter, Melinoë,and one son, Zagreus, so two kids well until you were an accident, but they loved you despite being an accident anyway! Having the god of the underworld and goddess of the underworld as parents is interesting but they're really chill and calm at times mostly persephone but who cares their better then zeus and hera who wouldn't want underworld parents?
One night, you were still a kid, and you had a nightmare, so what does every kid do when they have a nightmare? Go to mom and dad's room and stand in the doorway until a parent wakes up, so that's exactly what you did. You stood there some tears only for a minute before hades woke up and sighed, patting the bed
Hades: "Come on, little demon" He mumbled groggily
You walked over and climbed into the bed
