Masugu Tateishi works in the accounting department of Tsuda Confectionery, a sweets manufacturing company. His relationship with Yui MitsuyaâÂÂa coworker who joined the company at the same time but works in the planning departmentâÂÂis particularly hostile, to the point that their frequent clashes earn them the office nickname "mortal enemies". In reality, however, the two are deeply attracted to each other, and after a series of twists and turns, they finally become a couple.
Despite their feelings, Yui worries about workplace gossip and the challenges of office romance. To avoid scrutiny, they agree to keep their relationship a secret. Thus begins their covert life as coworkers-turned-lovers, all while maintaining their carefully crafted façade of mutual dislike in the office.
Like Enomoto's previous work, Fumino-san no Bunguna Nichijà Â, the series focuses on working adults. The series is based on Enomoto's own experiences as a company employee and a suggestion from the editor in charge to focus the series on a workplace romance.
