No, re-read the first scene with the headless dude (aka his father) where PP's dad found him.
I looked back to the pervious chapters to check his name...and Mook bum is prince's dad. So they are brothers? I still feel there is more to the story as to why he looks so different and is the prince penis ╮(￣▽￣)╭
Mook bum is Ryu's father. Haerang (the penis prince) was adopted by Mook Bum. All wolf sons were adopted, so none of the wolves are actual father and sons by blood.
Sooo haerang is garim little brother????
Or they confused the babies?
