Two alters, one body. One is possessive and assertive. The other is impassive and courteous. Kim Jongin has dissociative mental disorder due to the traumatic events that he suffered while growing up.
Jongin:Jongin is the elder among the two and his alter listens to him majority of the time. Jongin is well-mannered and reserved. However his heart is fickle and affections are fleeting, he tends to get bored easily. His facial expression are always neutral and has hard time expressing himself.He is the type of stay at home, reading books or trying out a new recipe during his leisure time.
Kai:Kai is a stark contrast to his older alter, he has no filter. Sarcasm and bluntness creates misunderstandings. He would rather go around at night for his wild escapades than stay at home. He is very obsessive and over-protective of his belongings, especially of Jongin. He loves Jongin excessively and lashes out every time he feels that the older's safety is at risk. They have a sibling-like relationship if that even makes sense.
