For anyone reading this manhwa, The term "personality" is already outdated and is no longer used.. and they are actually Identities and not Personalities (idk why the person translating this or the author is calling them personalities instead of Alters, because they are actually separated and have their own identity.) Also to add the disorder called "Multiple Personality Disorder" or "Split Disorder" Is outdated and it is now called "Dissociative Identity Disorder" DID for short ^^
