Tetsuya Kuroko, an ordinary Japanese high school boy, has a not-so-ordinary secret. +He has a system in his mind that can evaluate the shelf life of relationships with others. +This system can calculate the shelf life of family, friendship, love, and all emotions, and is accurate to the minute. +He didn't believe it at first. Later, he raised a hamster, and the system calculated it as 7 days. +The little boy eats and drinks well and takes good care of this hamster, and the little hamster is growing up healthily. As a result, on the seventh day, the little hamster got into the belly of the cat next door and left some body parts as a souvenir for Heizi. + After living for sixteen years, Heizi's emotional relationships were accurately predicted by this system algorithm. + Facts have proved that if a plastic friendship has a shelf life of only two years, even if it is a beautiful partnership between two brothers at the beginning, it will have to break up in the end, and there is no possibility of miscalculation. +However, at the age of sixteen, the sky-blue boy met someone. +The place where they met was an informal disco nightclub. +That man had a bad personality and a bad temper. The first thing he did when he saw Heizi was to pick up his collar and punch him down with his fist. +Icy blue eyes met the man's gaze. +In an instant, the system started running+The algorithm showed: 57+Their relationship has no minutes or seconds, only two numbers in the tens digit. +57
