Office Rivals is a visual novel by ParkedHearts, built with Ren'Py and presented in animated 2D CG art. You play a male protagonist whose late-night overtime fling stirs old feelings for his office rival, Nanako. The story explores romance and whether the two can reconcile and discover more than workaholic ambition. It is the second standalone episode of the Heart City Stories anthology, and Friendly Favours is not required to understand it.
The current build is v1.04, released August 7, 2026, and development is ongoing. It runs on Windows, Linux, and Mac, in English, without censorship. The Anniversary Update mostly expands Chapter 5, adding a proposal scene, a pre-wedding vacation, Nanako making amends with her parents, and a wedding party conversation scene. It also revises Chapter 1 dialogue to make the protagonist less spiteful and more repressed, and adds an option in the beach scene to ask a specific person to leave.
Developer's description
When one late night of overtime leads to a spicy fling, your long-lost feelings for your office rival unexpectedly resurface! What bottled up feelings will this predicament reveal? Will it reignite your long-lost feelings for Nanako? Where did it all go wrong between you and her? Will you reconcile with her to see if there's something more? And how will she eventually help you to reconnect what you've lost in touch with: that there is more to life than just being a productive workaholic?
