She returns to the day of college entrance examination application submission, when all tragedies have yet to come. This time, she strips away her innocence and weakness, moving step by step with caution and setting up defenses: changing passwords, keeping evidence, and laying traps to ruthlessly tear apart the hypocritical masks of the two.
