The dark BOSS, who had the fortune of becoming Earth’s last living human, brought with him his loyal, second last human to die, little brother to be reborn. What does he want to do after being reborn? Is it world domination or world annihilation? BOSS expressed, he was completely uninterested in these kinds of things, he only wants to die. In order for him to make his boss who always seeks death to continue living, little brother is completely unscrupulous, serving his boss to make him comfortable and cozy, then later helplessly discovered…. The BOSS’s behaviour is more and more abnormal!
