Spoilers
Over the course of the game, JJ Macfield is slowly revealed to have a secret of an ambiguous nature. Text messages sent back and forth between JJ and her mother reveal her mother's disapproval for young people of a "neutral" gender and her satisfaction in JJ as an "heir" and a "normal" child, to which JJ responds evasively.

At one point, JJ asks her mother not to enter her bedroom to clean it. When JJ's mother enters to clean anyway, she discovers clothes belonging to a young woman. JJ says that those are Emily's clothes, from when Emily stayed over. However, when JJ's mother attempts to return them to Emily's mother on the way home from church, and Emily's mother says the clothes don't belong to Emily.

JJ's mother later tells JJ that she read JJ's diary and discovered JJ's secret. This secret is still not explained to the player or described in any detail. However, it causes JJ's mother to insist that JJ see a counselor who is "good with dealing with young people." JJ sees the counselor to appease her mother. But things don't work out, and eventually, after snapping at Emily and becoming increasingly depressed, JJ attempts suicide.

Upon winning the game, players can play as Post-Clear JJ, with the appearance she has when she wakes from her dream at the end of the game. Post-Clear JJ also has newly voiced lines.
