An Affair My Sister in law’s

An erotic film about the revenge of a female intern who was abused at work.

A job offer is introduced to Choi Kyeong-ri, a job seeker, by her college senior, Park Chan-seong. Despite being only an intern for six months, she succeeds in being accepted into the job position. There is no other dream job like this, as she even receives a corporate card worth 3 million won per month just for her home decoration expenses. Later, after Kyeong-ri confessed to Chan-seong, the two started dating and eventually lived together. Meanwhile, Director Song, who usually only compliments Kyeong-ri for her appearance, slowly reveals her true colors and forces Kyeong-ri to give her massages, engage in lesbian activities, and even entertain investors, until they get caught by Manager Oh. Director Song receives sexual punishment from Manager Oh in front of Kyeong-ri. In the end, Kyeong-ri realized that she was actually hired only for hospitality work.
