Choi Yoon-tae was inspired to write this film in 2017 after he watched the interview of a female baseball player. He added that "when [he] told [his] wife that there is no current rule banning women from playing on a professional baseball team, she seemed surprised; so [he] thought it would be interesting to write a story on an aspiring female baseball player."[4]
