Kim Jiyun was raised in Seoul. She studied at Dankook University, majoring in creative writing for four years. She also attended the Korean Broadcasting Writers' Association training centre to learn how to write for screen, and later completed a drama course. One day, while walking down the noisy streets of Hongdae at night, she suddenly saw a laundromat with soft yellow lights on, and that gave her the first sentence of Yeonnam-dong's Smiley Laundromat, her first novel. She now writes full time.
