An alternate ending. On December 6, instead of getting in touch with his friends, Yu decides to once again confront Adachi alone, stating that he wants to help him. To this end, Adachi coerces Yu into destroying the threatening letter he wrote, instructing him to answer each of his calls if he does not want to be arrested for destroying evidence. As a result, Marie does not get in contact with Yu again, the fog never clears, and the investigation remains unsolved by the time Yu has to return home.
