Shiro and Kuro are homeless boys. Shiro thinks that all human beings are a failure of God, have no various “screws of the heart,” and have the missing screws of each other. "You're just talking big. You can't do anything," Kuro ran down an apparent young punk. Then Shiro admonished Kuro like the title. Those who cannot wrap up the weaknesses of the other people are letting them dry in spite of themselves. From a manga "Reinforced Concrete" 1.
