The Return Kim Minjeong is the child of a gardener who works for the Yu family. Since childhood, she has been looked down upon-her dignity constantly stepped on, along with her father's. They were treated like ants that could be crushed at any moment. Minjeong received endless mockery from the Yu family because of her condition-she was born intersex, having both male and female genitalia. Her parents wanted to have her female genitalia removed, but they couldn't afford the surgery. As for Minjeong, she identified more with being male-she was drawn to girls and preferred doing things boys typically did. But the cruelty didn't stop there. Karina Yu, the daughter of the Yu family, treated Minjeong like a toy-spreading rumors, humiliating her repeatedly, and calling her disgusting because of her condition.
