"Let me introduce (you to) my girlfriend") is a 2004 South Korean romantic drama film written and directed by Kwak Jae-yong, starring Jun Ji-hyun and Jang Hyuk.

One day while chasing a purse snatcher, she accidentally captures Go Myung-woo (played by Jang Hyuk), a physics teacher at an all-girls school, who was actually trying to catch the thief.

Kyung-jin is then given the job of escorting Myung-woo through a dangerous district, only to be distracted when she tries to break up a meeting between Russian Mafia and Korean gangsters.

Kyung-jin falls into a suicidal depression over his death and attempts to kill herself several times, almost succeeding when she throws herself off a building, only to be saved when a giant balloon floats under her.

Kyung-jin rushed out to locate the finder of the book, ultimately ending up in the train station, where she is saved by Cha Tae-hyun's character (credited as The Guy).

Windstruck shares the same leading actress and director as an earlier popular South Korean film, My Sassy Girl.

When Kyung-jin is chasing Sin Chang-su she tells a random citizen to act as a steppingstone to climb over the wall, just like when she accidentally steps on a runaway soldier (played by the same actor) when she and Tae-hyun visited the amusement park during her birthday.
