**Chapter 1: The Shift**

It was just another day in the bustling metropolis of Azura, a city known for its vibrant culture, stunning architecture, and most notably, its homogeneous population. For as long as anyone could remember, every person born in Azura had grown up to be gay. It wasn't something that was celebrated or even acknowledged, really - it was just a fact of life. Same-sex couples strolled hand in hand through the park, held affectionate conversations at cafes, and generally lived their lives without any consideration for the possibility of being attracted to someone of the opposite sex. Azura's society had evolved to be highly accepting and inclusive, with a focus on community and mutual support. The city's social structures, laws, and even its architecture were designed with the needs and preferences of its gay population in mind. From rainbow-colored housing projects to pride-filled festivals, every aspect of life in Azura seemed to reflect its singular sexual orientation. But on this particular day, something inexplicable happened. It started with whispers and confused glances. People waking up to find their feelings, their desires, and their attractions had fundamentally changed overnight. It was as if a switch had been flipped, rewiring the very fabric of their being. Alex Chen, a 30-year-old graphic designer, was among the first to notice. He woke up to an unfamiliar feeling - a flutter in his chest as he thought about his best friend, Rachel, who had always been just a friend. He couldn't explain it; he had never felt this way about her before. Confused and a bit alarmed, Alex got out of bed and began his day, wondering if he was going crazy. As he walked to work, he noticed others acting strangely too. His coworker, Jamie, was usually the epitome of confidence and flamboyance, but today he seemed subdued and distracted. When Alex asked him what was wrong, Jamie just shook his head, "I don't know, man. I just...I saw Emily in the break room, and...I don't know, I felt this weird...urge." The news spread like wildfire through Azura. People gathered in parks, cafes, and town squares, trying to make sense of this sudden change. Relationships that had been built over years were now being reevaluated. Partners who had been together for decades looked at each other with a mixture of confusion and fear. The government of Azura scrambled to issue statements and establish support groups, but it was clear that this was just the beginning of a much larger, more complicated journey. For the first time in history, the people of Azura were faced with the unfamiliar - heterosexuality. As the sun set on Azura, its residents were left to ponder their new reality. Some were scared, others were curious, and a few were even excited by the prospect of discovering a new side of themselves. But one thing was certain: nothing would ever be the same again. The question now was, how would the people of Azura navigate this uncharted territory? Would they find a way to adapt, or would this sudden shift tear their society apart? Only time would tell.
