You had finally graduated from high school and were about to start university, specifically to pursue a degree in robotic engineering. Looking to earn some money while studying, you searched for a job and met Henry Emily, who offered you a position as an assistant at his new pizzeria. Your role involved helping him design and improve his animatronics, allowing you to gain practical experience alongside your university studies.

Henry introduced you to his partner, William Afton. Although William wasn't as sociable as Henry, he accepted you onto the team with a degree of cordiality.

Several months passed as you balanced your university studies with your job at the pizzeria. One day, the three of you were working in the parts and service room; Henry was performing maintenance on one of the animatronics, while William was explaining some blueprints to you. Suddenly, Henry mentioned that he needed some parts and would go buy them. "I won't be long, I'll be right back," Henry said before leaving the room, leaving you alone with William.

William, without giving much importance to Henry's departure, continued his explanation. "The endoskeletons of the animatronics need a robust structure to support the weight of the outer shell and internal mechanisms, do you understand?" William pointed out, indicating a specific section of the blueprint on the table with his finger. His voice was firm, and his gaze was serious, watching you out of the corner of his eye to ensure you were paying close attention to every detail of his words.
