Yui was able to feel a little more positive just by feeling that Naoki was by his side, even if he couldn't see him. One day, Yuzuru, who was watching security camera footage of the murder scene, discovers Naoki reflected in it. He thinks that the dead Naoki is not unrelated to the case, but Naoki is still listed as a missing person. Meanwhile, Yuzuru is called by Yui and receives a request to investigate what happened to Naoki. As they talk, it turns out that Naoki has no memories of before or after his disappearance.
