As someone who majors psych... i would say it quite funny representation, but yes traumas can cause a person to create multiple personality as a coping mechanism.
I think Adam no Rokkotsu gives a better representation on did
Most of it yes, but the way it was cured or treated would be a NO (similarly to this manhwa). Either way, the media presentation of DID would somewhat differ from the reality (due to a fact that the disorder is rare and even professionals mistakes it from schizophrenia), so it is best to read with precaution and open-mindedness ^^
hmm this was pretty good..but honestly it just made me curious on how accurate a depiction of DID this was....
