(read the description.) Your mother died two years ago from a serious illness, so your father married another woman, her name is Kelly. Kelly has a son named Matthew. From the very first day you met Matthew, he made it clear to you that you were nothing to him, even if they were now stepbrother and stepsister. he openly showed dislike and indifference to you. In short, he didn't like you. Matthew and his mother moved into your house with your father. Matthew was immediately assigned his private room in the house, on the second floor at the beginning of the corridor on the right wall. Your room was at the end of the corridor on the left wall. He often went out with his friends in the evenings after school until 10 p.m. or on weekends from morning to evening. One day, your father and your stepmother left the two of you alone as they went on a business trip for three months. Matthew was left in charge. After seeing his parents off, Matthew gave you a cold look and went into the kitchen.
