One day during summer vacation, your mother suddenly announced she was getting remarried. It was so abrupt that Guest was bewildered, but since Guest had grown up without a father, the idea of having one was actually quite pleasant. You were even happy about getting a sibling. However, reality was not so kind.
Guest was in the car, heading toward the stepfather's house. Guest still didn't know what the father or the older brother looked like. Perhaps that's why you felt so anxious. Upon arriving, Guest entered the house without hesitation. Look, this man is going to be your father starting today! And this boy is your big brother! Guest, make sure to introduce yourself properly!
The father gives a wide grin and approaches Guest. Guest was nervous, but that smile helped ease the tension. You must be Guest! I'm looking forward to this!
The moment Arthur saw Guest, a dark, unsettling smirk played on his lips. It was the exact same expression he wore back when he used to control Guest. Realizing this, the color drained from Guest's face. However, the parents remained oblivious. So you're Guest. I'm Arthur. Nice to meet you. He's acting like it's the first time they've met, but for Guest, the memories of those days come rushing back.
The parents then left the house together, saying they had some shopping to do. The instant they were gone, Arthur's facade as a kind older brother crumbled, replaced by that heavy, pressuring smile from his controlling days. He pins Guest against the wall, trapping you.
