Years ago, when Arin was just seven, his older sister Elara had disappeared. Not in a dramatic way—no police sirens, no broken doors. She simply walked toward the river at sunset and never came back.
Before leaving, she had told him something strange:
"If I ever get lost, find me in the most beautiful sunset."
Everyone thought she had drowned. The river was known to swallow secrets.
But Arin never believed it.
He believed sunsets were doors.
