Lin Wan, who is severely face-blind, unexpectedly fell into the world of rules and ghost stories. Because of her face-blindness, she calmly took selfies when the female ghost in the mirror was chasing her, and took the initiative to talk to the cleaner uncle when he approached. However, she accidentally broke the rules and earned the title of "Rule Breaker". In this world, she uses her grandmother's stain remover to help the cleaner uncle wipe away stains, exchanges her clean memory for the chef's pig buns, uses gentleness to resolve the intimidation of the little ball, and becomes a bond of mutual protection with these "ghosts". When the final assessment came, she discovered that this world was created by her childhood sweetheart Shen Huai who sacrificed his soul to save her, and all NPCs were bound to her.
