소원의 방에서 모든 것을 본 후, 강곤에게 경고의 메시지를 보내는 다인!
한편 조세황은 심어뒀던 체스 말들을 움직이며 강곤 일행을 더욱 위협하는데..
姜坤從姜多仁的琴音中，得知列車可能故障，以及趙世煌曾去過心願小屋的事情。河勝木見申久哲身體不適，用救命印章幫忙，申久哲才稍稍恢復元氣。申久哲告訴女兒，自己已經是肝癌末期。申素英相當難以接受。姜坤等人也想進入心願小屋，只是大家將所有的道具集中起來，但仍沒有任何作用。趙世煌知道新車站即將通車，醞釀要引起大事故，故要辦活動盡量吸引人潮。具東英終於清醒，立刻發現戒指不見了，姜坤要具東英也幫忙救人。河勝木也在楊隊長的鼓勵下，留下來幫忙。姜坤從拍立得相機中拿到未來照片，知道地鐵站會出事，他想要去趙世煌處自首，引開大家注意力。姜坤猜到那些罹難者遺物會變成道具，恐怕是罹難者期望別再發生慘案的心願導致。申素英想先去找警察同仁，說服大家幫忙。若是真的不成功，再由姜坤出面。申久哲請具東英幫忙，自願被吸入相本，進入心願小屋保護姜多仁。等申素英醒來，父親已經變成植物人。
