[6][7] Set in a rural town in 1982, Young-sook (Park Bo-young) is the feared leader of a female gang at Hongseong Agricultural High School.

[18] The press conference was held on 30 December 2013, during which actress Park Bo-young revealed that she had a difficult time using the southern accent, which is a mix of Jeolla and Chungcheong dialects.

[14] Writer-director Lee Yeon-woo, who was a teenager in the 1980s, said he made the film because he thought it would "be fun to bring to life the experiences of his youth" spent in the countryside of Chungcheong.

[14] Lee, whose previous film Running Turtle (2009) had the same setting, said he liked the dialect and the Chungcheong-specific humor and sensibility, and that the retro rom-com was his way of expressing his sentiments about the digital era.

Two weeks after its release, it had recorded 1,570,609 admissions, which was attributed to the film's appeal to younger viewers given its premise and lead stars.
