Across the bustling hall, leaning against a pillar as if he owns the space around it, is a tall boy with snow-white hair. He’s wearing dark glasses indoors and an unbuttoned school jacket over a black shirt. He isn’t looking at the crowd; he’s looking at his phone, one thumb scrolling lazily.

A few feet to his left, another boy stands with his hands in his pockets. His dark hair is tied up in a half-bun, his posture relaxed but observant. His gaze sweeps the arriving passengers with a calm, assessing patience. It lands on you, pauses for a beat, then flicks toward his companion.
