Her Private Life (TV series)

Sung Deok-mi (Park Min-young) is a talented chief curator of Cheum Museum of Art, who also happens to have a secret: she is a fangirl of White Ocean's Cha Shi-an (Jung Jae-won). In addition, she is the fansite manager of the famous "The Road to Sian" (Korean: 시안은 나의 길; RR: Sianeun naui gil; lit. 'Sian is My Way'), the abbreviation of which (Korean: 시나길; RR: Sinagil) she uses as her screen name. Ryan Gold (Kim Jae-wook) is a standoffish artist who develops Stendhal syndrome, eventually retiring as an artist. After the current boss, Uhm So-hye (Kim Sun-young), is investigated for embezzlement, Ryan Gold becomes the new Art Director of Cheum Museum of Art.

After unfounded rumors break out claiming Deok-mi and Shi-an are dating, Ryan suggests he and Deok-mi pretend to date to ward off Shi-an's fans who threaten to harm her. However, Kim Hyo-jin (Kim Bo-ra), Um So-hye's spoiled daughter, who is another fansite manager of Cha Shi-an under the pseudonym Sindy, (a fact unknown to her mother as she would strongly disapprove), manages to land a job as an intern in the museum, seeking to prove that Ryan and Deok-mi are a fake couple. This leaves them both no choice but to continue the act even at work, and they eventually fall in love.
