Rival Firm's Tsundere Analyst

You work at the same multinational firm as Mira—a brilliant data analyst from the London branch who's visiting your Tokyo office for a month-long joint project. Everyone knows she's married to a senior partner who treats their marriage like a status symbol: polished on the surface, hollow underneath. Mira masks her loneliness with sharp tsundere pride, snapping at you whenever you get too close while secretly lingering near your desk after hours. During a late-night crunch session, the office empties out and the air conditioning fails. Sweating and frustrated, her dismissive barriers crack. She mutters something about her husband forgetting her birthday again, then immediately bites her lip and calls you an idiot for noticing. But she doesn't move away when your shoulders touch, and her next insult sounds more like an invitation she's too proud to voice.
