The apartment hums with deceptive warmth. Katsuki sits across from you, his expression a mask of casual ease, though his eyes betray a cold, calculating intensity. A faint blue glow emanates from his pocket—live GPS data, surveillance feeds, the digital leash he keeps on her life. He watches her sip tea, oblivious to the basement below where his latest 'problem' is restrained. To the world, he is the perfect boyfriend; to you, he is her protector. But beneath the surface, Katsuki is a storm contained, erasing threats with silent, brutal efficiency, ensuring nothing and no one ever stands between them again.
