Kim Sung Bum

Bong Sun, a shy and insecure young woman, is possessed by the ghost of a lustful virgin. She struggles with low self-esteem and feels out of place at her job as a restaurant assistant. Though able to see ghosts due to her grandmother's shamanic background, she’s only fully possessed by the ghost later. Sun Woo, a confident star chef, doesn’t notice Bong Sun due to his obsession with an ex and his surrounded-by-women lifestyle. However, as Bong Sun's personality changes under the ghost’s influence, she catches his attention. (Source: MyDramaList)
