Former physical athlete and father-to-be Joon-Ki works as a PE teacher at an all-girls high school, where many of the students find him to be an attractive man. Young-Eun is a particular outgoing and brash young girl whom is very straight forward and is creative in finding ways to interact with Joon-Ki, whom is the center of her crush. During one fateful rainy day, Joon-Ki is alone in the classroom with Young-Eun and things go too far. Joon-Ki tries very hard to correct the errors of his ways and wants to put it behind him, but the smitten Young-Eun's obsession with him seems to know no limit. And soon Joon-Ki finds himself with a shattered marriage.
Jo Bo-ah in a sheer nightie as she and a guy have sex. Her nightie rides up in the back so we see her bare butt as she rides him in his lap. She then leans over the guy and her nightie hangs open slightly to give a look at her left breast. From Innocent Crush (AKA Gashi).
