A modern social animal woman was forced to wear the shell of a vicious stepmother, only to find that the harder the shell was, the more her family could see her softness. Every verbal harshness she expresses is a flustered self-justification in her inner voice system; every superficial indifference she expresses explodes into the most fiery confession in the ears of her family. The core conflict in the book is not the confrontation between good and evil, but the mismatch between "expressing" and "being heard" - she thought she was perfectly hidden, but she didn't know that her family members within five meters had already heard through her panties.
