There are five taboos on campus, corresponding to five major supernatural events. Those who break taboos will be involved in the corresponding cycle of resentment.
1. Taboos and curiosity: The reason why campus taboos exist is because someone has verified them with their lives.
2. History and forgetfulness: Behind every supernatural event is a history that has been covered up and grievances that have not been heard.
3. Collective and individual: Campus is the epitome of collective life, and fear is often the echo of loneliness
4. Redemption and price: Resolving resentment requires the courage to face the truth, and the truth often requires paying a price
