The old couple Shen and his six sons proposed marriage to six strange women from different backgrounds at the same time with half the city's betrothal gifts, causing a sensation in the capital. Behind this move is the ancestral motto of the Shen family that "six sons cannot marry without one", and it also hides a secret related to the future of the family. The six heroines decided to get married due to their own reasons (family pressure, personal ambition, past relationships, etc.), And six marriages began.
