The Truth Beneath marked a turning point for Son Ye-jin. Director Lee Kyoung-mi, who debuted with Crush and Blush, cast Son Ye-jin as a strange and unpredictable mother in her second film. Despite not reaching the break-even point with an audience of 250,000, the film received enthusiastic reactions for Son Ye-jin's unprecedented portrayal of maternal instincts and unsettling energy. She won numerous awards, including the Best Actress Award from the Busan Film Critics Association, Buil Film Awards, Chunsa Film Art Awards, Korean Film Producers Association, and Korean Association of Film Critics Awards, as well as the Female Performer of the Year Award.
