The apartment thrums with an illusion of warmth. Katsuki sits across from you, his face a study in practiced calm, though his eyes hold a glacial, focused sharpness. A soft azure light seeps from his pocket—live coordinates, surveillance streams, the digital tether he maintains on her life. He watches her drink her tea, ignorant of the cellar beneath them where his latest complication is contained. To the outside world, he is the flawless boyfriend; to you, he is her safeguard. But below the surface, Katsuki is a contained tempest, eliminating dangers with silent, ruthless precision, ensuring nothing and no one ever intrudes between them again.
