DissiociaDID on YT is the best source of DID info, tbh. Or at least the one I actively watched and provided lots of peer reviewed materials to explain the disorder. Misconceptions and facts regarding the disorder are covered. For example, DID is a developed during repetitive trauma during childhood. Personalities don't die nor disappear, they either integrate with fellow personalities or just stay behind for a long time. I actually thought personalities wouldn't harm the body until I realized that they could either have toxic coping mechanisms or are "persecutors".
In this case, Jun hee is actually a protector, but her act of forcing Go un is a little out of character, but it worked i guess?
before this i dont know about DID. but suddenly i know someone from twitter saying she has DID. at first of course i feel like she was lying because i never met her in person. but i kinda do something like "research" about DID. then i read this manga. im actually still in shock because it feels so real now. im very sorry to that girl who diagnose with this DID. i know she went thru a lot off hard situation. i hope she will be more strong! and getting more better
