The film follows young bank clerks Lee Dong-hee (Lee Min-ki) and Jang Young (Kim Min-hee (actress, born 1982)) who have just broken up with each other. They work at a local branch of Standard Chartered Korea, and their seemingly nasty split turns scandalous in the office. After going through a period of irrational behavior, including physical fights and Young’s impulsive one-night stand with a mutual colleague at work, the two decide to give their relationship another try. Once again, they are madly in love.
