Min-ji

Min-ji, full name Jeong Min-ji (정민지), is a minor character in Train To Busan.

She is portrayed by Woo Do-im.

History
Min-ji is a Korean-Japanese train attendant girl on the train where the film is mainly set. She was born in 1992 on September 7 in the city of Fukuoka, Japan with Korean ethnicity, and moved back to South Korea when she was a teenager. This is all the producers have told us about her backstory.

Min-ji first appears in the movie as passengers are boarding the train. She stands besides the train doors welcoming aboard passengers with a passenger asking her a question which she answers. Later, as Min-ji is walking around the train preparing for its departure, we see her come across Ki-chul who tells her to adjust her attendant uniform. Embarassed, she adjusts her attendant uniform as requested and keeps preparing for departure.

After the train departs, Min-ji is shown walking through the connection between one train car and another, where an infected woman is lying on the ground dead and turning into a zombie. Concerned for the woman's health, Min-ji quickly grabs her radio and asks for help in checking the infected woman's health situation, where she gets no response. Worried, she turns her back on the woman and fiddles with her radio while the woman turns into a zombie. When she notices the zombified woman, a horrified Min-ji drops her radio and staggers backwards. She is attacked and bitten by the zombie, becoming infected and turning into a zombie then attacking more people, starting the zombie outbreak on the train.

Trivia

 * Min-ji's last name, Jeong (정), is only known by reading the name tag she wears on her uniform in the movie. The movie's producers never made an additional statment that reveals her last name.
 * Min-ji is fluent in Japanese in addition to Korean, making her possibly the film's only bilingual character.
