That was the night Eren chose a coin engraved with "I stayed because I was afraid of being alone." He pressed it into the lighthouse's seam. The light tilted; the glass panes sweating a fine rain. The lighthouse, which had always been impartial, showed him a scene he had avoided forever: his younger self, dancing badly at a festival, perfectly alive and loved—and then leaving the woman who once loved him because the sea promised a different life. The memory came with an ache so acute Eren found himself laughing and crying at once.
