Karen Inuyama, a lively office worker obsessed with lean, muscular physiques, spends her breaks admiring muscle magazines. Her coworker Takuma Hosokawa, a seemingly slender and bookish type, constantly interrupts her with his nagging, making him irrelevant to her interests. During a casual after-work drinking party at Hosokawa’s place, a mishap reveals his secret: he has a perfectly toned, lean-muscular body. Stunned, Karen impulsively asks to touch his muscles, leading to a playful agreement where she becomes his exclusive masseuse. Their quirky arrangement sparks humorous exchanges and a budding connection, setting the stage for a lighthearted workplace romance. (Unreviewed summary by Grok 3)
