Known for blockbuster films like Scandal Makers and A Werewolf Boy, Park Bo Young returns to television for the tvN supernatural romantic drama Oh My Ghost (a.k.a. Oh My Ghostess). Portraying dual personalities as a mousy young woman possessed by a bold ghost, the petite actress acts up an adorable storm and cooks up sizzling chemistry with Jo Jung Suk (You Are The Best, Lee Soon Shin). Kim Seul Gi (The Idle Mermaid) co-stars as the saucy spectre in question while Im Ju Hwan (What's Up) plays a mysterious police officer who may be linked to her past life.

Frequently haunted by ghosts, perennially tired and timid kitchen assistant Na Bong Sun (Park Bo Young) goes through life with her head hanging down. She is secretly in love with cooking and with irascible chef Kang Sun Woo (Jo Jung Suk), the owner of the restaurant she works at, but she's too introverted and insecure to make any headway in life. Everything changes when Bong Sun gets possessed by sassy spirit-on-the-run Shin Soon Ae (Kim Seul Gi) who has a grudge to settle: she needs to lose her virginity. Her time is limited and she's set her sights on Sun Woo! Meanwhile, a little ghostly intervention may be exactly what Bong Sun needs to turn her life around.
