I'm only about fifteen chapters into 'Shall We Work Overtime?', and honestly, the title is kind of misleading if you're expecting a straightforward office drama. It's actually a fantasy romance wrapped in a corporate setting. The main character is a regular office worker who accidentally summons a demon, not for world domination, but to help him clear his impossible backlog of paperwork. The demon, who expected a grand, evil purpose, is instead forced to use his infernal powers for spreadsheets and presentations.
That core setup is where the charm lies. The plot isn't about climbing the corporate ladder in a traditional sense; it's about this absurd yet weirdly functional partnership. The human is trying to survive his toxic job without selling his soul (literally, though he kind of already did), and the demon is trying to understand modern human bureaucracy, which he finds more confusing and terrifying than any hellscape. Their dynamic shifts from master-servant to something more like begrudging colleagues, and maybe more. The central plot question seems to be whether they can achieve their respective goals—the human wanting a normal life, the demon wanting power—through this bizarre arrangement, or if the boundaries between their worlds will completely collapse.
