Sigma never had a happy childhood. Since he was 5 he was dragged around as a slave. Now he's 13, his reading and writing are poor and he can't even do the easiest math.Cuffs on his hands, a shock collar on his neck. Another action,they bid on him. Again, 100000000$ for him. Yet he is suprised to see how the person who bought him looks at him. As if he was a human, not a slave. He is still just a child after all. who doesn't know what meal is, who doesn't know how normal life looks
