Chosen AU: Personality Switch AU.

Scenario:

Every year, there was this one day where you'd swap personalities with someone and would have to stay near them.

(A) and (B), at that time, were stood in a queue right next to each other.

Personalities are like orbs and so they would hover out of you and move on to someone else.

(A) wanted to do their favorite thing but was stopped by (B) 

as they had to be near each other and (B) hates (A)'s favorite thing to do.
