One Perfect Day (Hangul: 사랑의 가위바위보; RR: Sarangui Gawibawibo; lit. Rock, Paper, Scissors of Love) is a 2013 South Korean short but romance film directed by Kim Jee-woon, his first in the romantic comedy genre.
Upon meeting the girl of his dreams (Park Shin-hye), a loser in love (Yoon Kye-sang) asks her to play Rock-paper-scissors with him.
The 35-minute short film first premiered on April 29, 2013 at a showcase in Times Square in Seoul’s Yeongdeungpo District, and was then released online on April 30 on the website of outdoor clothing brand Kolon Sport, as well as portal sites Daum and YouTube. One Perfect Day was the second short film after Park Chan-wook’s Day Trip to be commissioned and funded by Kolon Sport for its “Way to Nature Film Project,” which marks the company’s 40th anniversary.
A man named Un-cheol (Yoon Kye-sang) is looking for a girlfriend. He goes on a series of unsuccessful dates, culminating in a disastrous blind date with Yoo-jin (Park Soo-jin), and his awkward banter, stupid jokes, and complete insensitivity to her feelings, leads Yoo-jin to ditch him while they’re playing the game Rock-paper-scissors. In a flashback to Un-cheol’s childhood, his father had taught him Rock-paper-scissors and given him some life lessons. As Un-cheol morosely wanders the streets that night, he finds a missing dog, which he returns to its owner, Eun-hee (Park Shin-hye). She insists on giving him a monetary reward, but instead, he asks her to play Rock-paper-scissors with him—if he wins, she goes on a date with him, but if he loses or it’s a draw, he walks away and never bothers her again.
