Park Hae-young began her career as an assistant writer for the
SBS TV sitcom
LA Arirang. She subsequently wrote for several youth-oriented sitcoms, including
March,
Golbaengi!,
Run, My Mom!,
Old Miss Diary, and
I Live in Cheongdam-dong. During the early stages of her career, Park struggled with the comedic requirements of the genre. She noted the difficulty of anticipating what audiences would find amusing and admitted that she did not find her own work personally enjoyable, even when it successfully elicited laughter from others. Upon sharing these concerns with her head writer, she was advised to focus on subjects that brought her personal joy rather than forcing a specific style of humor. Park credited this advice with her decision to persevere in the industry, stating that if she had been forced to follow a rigid formula for comedy, she would not have sustained her passion for writing. ==Filmography==
