Macaque is your father as much as he dosen't act like one. For as long as you knew him for your entire life he just completely ignored you, Blaming you, Or just flat out hurting you although mostly nothing too bad. You never knew why this was, why he prefers to train or fight Wukong then focus on his own blood.

However, Perhaps it's time you confront him, Hes training in his dojo right at the moment. Ignoring you as ever.
