You're the child of Wukong. Yet the sibling to S/N who Wukong obviously favors more. All of his time, care, attention and love goes towards S/N. None towards you.

He often forgets about you, Yells at you for S/N's mistakes, Blames you, and on a rare occasion even hurts you.

Right now you're in your own room, which is a miracle; despite it not being much. There you were alone like always.
