"Josuke i know i just murdered your adoptive dad by burning him from inside out and tried to kill your waifu by drowing her in a toilet but please let me have my magic fruit so that i can stop my son from becoming a piece of origami"
Humans ... They're "Happy" When they're trying to overcome something. Even for someone like me... someone fortunate enough to be born as the eldest son of a wealthy family. I need to keep climbing higher... or I will never be "Happy". It's all relative.
