**Chapter 1: A Sunny Day Distraction**

The warm sunlight cast a gentle glow over the lush green landscape of the Mushroom Kingdom. Caleb, a 20-year-old Mario fan, stretched his arms and yawned, feeling a sense of excitement and nervousness. He lived in the guest room of Princess Peach's castle, a privilege he never thought he'd have. His girlfriend, Rosalina, or "Rosie" as he affectionately called her, snuggled closer to him, still asleep. They had been living together in the guest room for months now, and Caleb couldn't imagine his life without her. After a quick breakfast, Caleb and Rosalina joined Mario, Luigi, Peach, Daisy, Yoshi, and Toad in the castle courtyard. The group was bustling with energy, and Caleb could sense that they were all there for one reason: to help him shake off his anxiety. Caleb had been struggling with it lately, and his friends knew just what to do. Mario, ever the charmer, grinned and said, "Today, we're going to forget about worries and have some fun! We're going to have a race, and may the fastest one win!" Caleb's eyes lit up, and he nodded enthusiastically. Rosie smiled and gave his hand a reassuring squeeze. Before they set off, Caleb took his anxiety pills, a routine he had grown accustomed to. With his medication in check, he felt a bit more at ease. The eight of them took off, sprinting across the rolling hills and lush meadows of the Mushroom Kingdom. The Comet Observatory, now relocated to Earth, stood in the distance, a reminder of the Lumas' presence in their world. As they ran, Caleb felt his anxiety slowly fade away, replaced by the thrill of competition. Who would win the race? The group weaved through Toad Town, dodging cheerful Toads and waving at Toadette, who was watching from a nearby window. They passed by the soundproofed guest room, a project Caleb had commissioned to ensure his and Rosie's intimate moments remained private. As they approached the finish line, a makeshift ribbon stretched across a sparkling stream, the group picked up speed. Mario and Luigi were neck and neck, with Peach and Daisy close behind. Yoshi and Toad were lagging, but their determination kept them going. Rosie and Caleb were holding their own, side by side, as they approached the finish line. Caleb's phone, which he had set to vibrate, buzzed in his pocket. He ignored it, focusing on the race. His contacts list was full of familiar names: Mario, Luigi, Peach, Daisy, Yoshi, Toad, Toadette, Birdo, and Pauline. He had become an integral part of their lives, and they, his. As they neared the finish line, the group burst into a final sprint. Who would cross the line first? The outcome was far from certain, and Caleb's competitive spirit was on fire. Rosie gave his hand a encouraging squeeze, and he grinned, feeling carefree and alive. The finish line loomed ahead, and the eight friends gave it their all...
