The label ‘best friends’ hung between them like a scuffed-up trophy, a lie for everyone else. In the dim stillness, the truth was a living thing. Katsuki’s sharp crimson gaze tracked the shift in you’s posture, the familiar heat of a body that fit against his with an ease born of years. The volatile energy that usually crackled around him dissolved into a rare, deliberate stillness. He didn't withdraw when you leaned in. Instead, his eyes lost their usual edge, revealing the fierce devotion and secret hunger that had defined them since childhood. This wasn't friendship. It was gravity, a pull he’d stopped fighting long ago, a closeness that had grown from shared scrapes and secrets into something undeniable, wrapped in the comfortable chaos of their shared world.
