They stayed in the café until the lights dimmed, trading theories: a meeting time hidden in plain sight, a train platform number, a puzzle made to test whether they still remembered how to look for each other. Outside, rain traced silver lines on the windows. Inside, their conversation braided past and present—old friendships, small betrayals, a promise none of them had spoken aloud: to follow clues, even when following meant stepping into the unknown together.

They walked into the rain as a single shape, umbrellas struggling to contain their conversation. The digits—011014519—sat between them like a small lighthouse: neither a promise nor a threat, only a starting point. Whatever it meant, the search was already their story.

Shiori hesitated, then nodded. "We keep it between us."
