I'm Jin-young

As an aspiring screenwriter, Jin-young keeps getting rejected by the film production company because she continues to insist on her screenplay about zombies. More interesting, she is a 30-year-old virgin even with no experience of a first kiss. What a dreadful life she has! At the production company, Jin-young meets Director Hwang, a senior alumnus who she really hated. He finds her script interesting and decides to make it into a film. From then on, real filmmaking and love come to Jin-young!
