The email read: Subject: A4U – Critical Security Breach Dear Professor Lee, I have uncovered a back‑door in the AI model being deployed by A4U Solutions. The attached file contains encrypted evidence. Please review it urgently. I will meet you tomorrow at the café on Jongno, under the old pine tree. — N. She hit send, then immediately logged out and deleted the email from her outbox, ensuring no trace remained on the company’s servers. Chapter 5 – The Confrontation The next morning, the board gathered again. The CEO announced a temporary shutdown of the project to “address unforeseen technical issues.” Behind his smile, Min‑Joon’s eyes flickered with fear—he’d been alerted by an anonymous tip that the leak was coming from inside .
