A simple, elegant gesture between a man and a woman threatens to invite embarrassing consequences in director Ryoo Jang-ha's whimsical Korean-language seriocomedy Hello, Schoolgirl!. Although low-tiered civil servant Kim Yeon-woo (Yoo Ji-tae) just recently turned thirty, he retains an innocence and a naivete that set him apart from other men his age. Fully displeased with bachelorhood, Kim spends innumerable hours on dead-end blind dates, combing local candidates for a suitable wife. Then he meets Han Soo-Young (Lee Yeon-hee), a neighbor who lives downstairs. She's upbeat, quirky, charming and beautiful; she's also still in high school, and thus over ten years younger than Kim. Kim takes an ill-advised step when he runs into Han one morning - she's making her way back home after reaching school and realizing that she forgot her mandatory necktie. As an innocent courtesy, Kim offers to save Han time and trouble by lending her his own tie; that marks the first step in a relationship that spells overwhelming trouble for both.
