Ahn directed the Korean dramas Something In The Rain (2018), Roses and Bean Sprouts (1999), Ajumma (2000), Behind the White Tower (2007), How Long I've Kissed (2012), Secret Affair (2014), and Heard It Through the Grapevine (2015).
In 1986, he and fellow cinephiles from Sejong collaborated on the 22-minute short film In Praise of Idleness; the crew consisted of Yoo Ha as the director, Kim Sung-su as cinematographer, Ahn handled the lighting, and poet Jin Yi-jeong wrote the screenplay.
[16] Kim Hee-ae played the protagonist, a middle-aged housewife who struggles with the unforgiving expectations of her husband (Jang Hyun-sung) and his status-obsessed family, then finds a kindred spirit in her son's dentist (Lee Sung-jae).
Praised for its richly drawn characters and the realistic depiction of affluent Korean parents' obsession with their children's academic achievements, the show was a hit, reaching 4% viewership ratings.
[21] Ahn returned to network TV in 2015 with Heard It Through the Grapevine, a black comedy dissecting the class divide as the teenage son of a wealthy, powerful family brings home his pregnant girlfriend (played by Lee Joon and Go Ah-sung).
