Not everyone experience disassociate disorder the same way. For some people it can happen slowly and for others under the right pressures, in a instant. And how i took this chapter, it took years of abuse before it happened. His father constantly comparing him to his brother, made him create the brother personality.

I wish they did a better job and portraying disassociate disorders. Like id be nice id the creation of the "hyung" personality was more gradual and they mad his infatuation (with the kiss as a child) make more sense
