Tutoring a Student of the Same Age) is a 2003 South Korean romantic comedy film starring Kim Ha-neul and Kwon Sang-woo.

Unglamorous Su-wan is a sophomore in college who gets hired to tutor rich troublemaker Ji-hoon, who is repeating his senior year of high school for the third time.

Park Yeon-seon's screenplay was based on a series of stories posted online in 2000 by a real-life English literature major named Choi Su-wan about her experiences in tutoring a high schooler of her same age.

The friend, Kim Ji-hoon's mother, wants a tutor that will make her son study so that he can pass his high school graduation exams.

He has recently transferred to Surim High School, and manages to offend Lee Jong-soo (Gong Yoo), "king" and best fighter there.

He continues to brawl at Surim, including beating up a member of the high school gang for stealing from his younger brother Se-hoon.

Ji-hoon's father, Kim Bong-man threatens to send him back to the US if he continues to get into trouble with his fighting and bad grades.

In 1999, Choi Su-wan was a 19-year-old college student majoring in English and Korean languages, when she agreed to tutor a rich delinquent her own age named Kim Ji-hoon.

Due to its popularity, it first appeared in print in the monthly issues of a local magazine, under the title He and I written by Shim Hye-jin.

That same year, film company Corea Entertainment purchased the rights, and screenwriter Park Yeon-seon adapted it into a screenplay.

Comparisons were made to My Sassy Girl (2001), another successful romantic comedy about young people who came from different backgrounds, that was originally serialized on the Internet.

Though promoted as a sequel, the film contains completely different characters, and only follows the basic premise of a boy and girl of the same age that happen to meet as student and tutor, and later fall in love.
