Jiang Lu, a socially fearful girl who has been bullied by school bully Fang Yan for a year, unexpectedly awakens the ability to read minds and becomes a candidate for heaven's "judge of good and evil in the world". The first level of the divine test told her: Bullies may also have been victims. When she used her mind-reading skills to hear Fang Yan's inner words, "I'm protecting her," a fateful game about redemption and counter-killing officially began. She can judge good and evil, but she cannot judge her own accelerated heartbeat - because the system gives a final warning: Redeem the bully, and you may fall in love with him.
