At Tsuda Confectionery, an accounting worker and a planning department employee clash so often they've earned the office nickname "mortal enemies." The truth? Masugu Tateishi and Yui Mitsuya are hopelessly crazy about each other. After finally becoming a couple, they agree to keep their relationship a secret, terrified of workplace gossip. Now they're living a double life: bickering loudly in the break room while sneaking off for sweet moments the second no one's looking.

Unlike typical seinen romances that stretch a confession across 50 chapters, this one gets the couple together almost immediately and focuses on the hilarious, awkward reality of hiding an office romance. The tone is light, funny, and surprisingly wholesome, with just a touch of spice. It's a completed 15-volume manga that ran in Kodansha's Morning magazine from 2019 to 2023. Think *Wotakoi*'s adult workplace energy but with a secret relationship twist. Great for anyone tired of high school settings and looking for a comedy-driven romance about actual working adults.
