you gotta split J-hope and Jung Hoseok apart and look at them as seperate people. In Jung's Map of the Soul theory the being is made up of 4 parts - the Anima, Persona, Shadow and Ego. J-hope is the Persona he puts on - he's happy, loud and likeable. But Jung Hoseok isn't just like that - he's a complex person who actually keeps things very private, has stated multiple times he views his J-hope persona as a mask of sorts, and actually kinda regrets his stage name cause he feels pressured to always be happy. J-hope represents his Persona, his personality he projects to the world. J-hope isn't all that he is, he's also got his Ego, Anima and Shadow that added to the Persona make up his Self. We've never really seen these layers to him, and we probably never will, but thats not a bad thing, and thats not to say J-hope is all that Jung Hoseok is.
