Four close friends traveled far to another place to serve as bridesmaids for the bride Shen Wei, but encountered disdainful and perfunctory arrangements. They no longer stay silent, preserve evidence, leave overnight, and use facts to respond to false remarks, firmly defending their own dignity. After the disturbance, the bride publicly apologizes and bears the consequences, and the groom also chooses to distinguish right from wrong. Having gone through this trial, the four girls understand respect and boundaries even better, and cherish each other even more.
