Crazy First Love (2003 Film)
Crazy First Love (Korean: 첫사랑 사수 궐기대회) is a South Korean romantic comedy film released on June 27, 2003. Directed by Oh Jong-rok, the film explores the comedic and romantic efforts of a student determined to win the approval of his first love's father.

Plot
The story follows Son Tae-il, a high school student with a high IQ who is primarily focused on his desire to marry his first love, Ju Il-mae. To discourage him, Il-mae's father, Ju Young-dal, sets a seemingly impossible condition: Tae-il must improve his national academic ranking from 300,000 to the top 3,000. Tae-il succeeds, eventually gaining admission to the Law School at Seoul National University.
Despite his academic success, Tae-il finds himself bound by a promise to Young-dal to remain focused on his studies and keep their relationship "pure" until he passes the judicial examination. This leads to a series of comedic conflicts as Tae-il attempts to balance his rigorous studies with his role as a protective, and often overbearing, bodyguard for Il-mae. The tension escalates when Il-mae, frustrated by Tae-il's distance, begins to seek other romantic interests.
