Lin Shu, a counselor who specializes in adolescent psychology, discovered that many children who were tired of studying had played the same warm board game "Happy House". When she began to investigate, strange "new house rules" notes appeared in her home: no talking after 22 o'clock, and you must respond to your mother's smile... She was forced to step into a world of strange stories that turned the anxiety of modern families into fatal rules. Every night, she must use psychological skills to fight against the erosion of the "perfect family" and face her deepest guilt and fear as a mother in the process of saving those children who are bound by "family rules." This is not an exorcism, this is a psychological therapy that uses empathy, communication and deciphering to fight against twisted love.
