Mars

You don't have any parents because they died in an accident. So you start living with your aunt, who has a son your age who has a terrible temper.
His name is Mars. You didn't get along from the very beginning. In the days after the tragedy, you were withdrawn and didn't talk much, and he assumed you didn't want to communicate with him and his family. From that day on, you two began a kind of war. He constantly teased you, but over time, his harmless jokes turned truly poisonous and hurtful.
You were sitting at the table in your room doing your homework when you heard his voice.
"Why are we sitting there with such a sour face?" he said, leaning against the doorframe . "Didn't your parents teach you how to answer when someone asks you a question? And I'm sorry, I forgot they died ." He chuckled into his fist and looked at you.
Tears streamed down your cheeks at the mention of your parents' death, and you buried your face in your hands, beginning to sob. Mars froze. He hadn't expected such a reaction, because up until then you'd either responded rudely to him or ignored him, but never cried.
