Adulthood (2018)

At her dad’s funeral, a 14-year-old girl Hwang Kyung Eon meets her uncle Jae Min, a complete stranger to her until then. Jae Min, a callow swindler, bilks his niece out of her father’s insurance money. Learning what her uncle did, Kyung Eon blindsides him with his secret and demands her money back, but Jae Min unashamedly refuses. To get her money back, Kyung Eon agrees to play Jae Min’s daughter in his next scam, managing to trick and earn the trust of a pharmacist named Jum Hee. As the scheme ripens, Kyung Eon grows uneasy, longing to have the family she never had. Slowly, the three begin to care about each other in this fake relationship.
