Summary
Kent was in his thoughts now—an echo, a minor note out of tune with the rest of the orchestra. Lex finds himself watching for him. Not just in bylines. On the floor of charity galas. Behind a camera crew at city pressers. Always calm, always watching. He’s not the first to linger in Lex’s shadow. But he’s the first Lex can’t classify.
Animosity folds into intimacy, built brick by brick in stolen moments and unspoken truths. Every touch deepens the lie between them. When the truth comes out, the fall is not sudden. It is slow. Inevitable.
