Since then, the narrator has been spying on his brothers. One morning, he goes for a morning run. He notices that the elder brother takes his younger brother for a walk in the morning. The younger brother does not die, but is resurrected. The narrator is sure that he was not mistaken the day before. He runs into his brothers again, and the younger brother gives him a diary. He says that he is going to work harder like his brother. The diary is a magical one, and if he dies, it will record the day he dies. Since he became ill, he has had suicidal tendencies. He has switched the diary from his older brother's to his own. The reason why his brother is able to live so long after a suicide is because the diary is there. He flips through the diary and sees that it has been torn away. He realizes that his brother gave him the diary when he was ill, and he flips through it to find that it is missing. He then flips through a few pages and finds that the older brother has died. He fed the poison to his dog, which died.
