Sophomore university student Su-weon (Kim Ha-neul) has been struggling with financing her education since she began her degree program, which has forced her to become a part-time tutor. In need of a new student since she was forced to quit her previous assignment with a group of sexually aggressive young men, Su-weon, with her mother's assistance, finds a new job working with the son of a rich acquaintance. The young man, Ji-hun (Gweon Sang-woo), has spent the last three years studying in the United States and -- due to his ambivalence toward his studies -- he has failed to graduate as a senior in each of those three years. For his part, Ji-hun would rather not have anything to do with his new tutor and attempts to scare her away. Meanwhile, Su-weon is just as determined to accomplish her objectives with Ji-hun, and as the two wage psychological warfare with one another, an unexpected friendship and romance begins to bloom. My Tutor Friend was a smash hit in South Korea upon its release in early 2003, topping the box-office charts for five weeks after its debut.
