Small girl is a fan-fiction story about the song of Lee Young-ji and Doh Kyung-soo the "Small girl". Young-ji is a woman who is so insecure about herself. She always doubted a man's feelings toward her because she's aware she doesn't fit the beauty standards in our generation. That's why even though Kyung-soo expresses his feelings towards her, she hardly believes it because she's not like the other girl with a soft voice and personality.
