Tatsuya had always been hesitant to use his powers in front of others. But after his experience in the physical exercise period, he began to feel more confident about using them for good. He was fast and agile, and he knew that he could help people in ways that others couldn't.
One day, as he was walking down the street, he saw a little boy crossing the road with his mother. Suddenly, a truck appeared out of nowhere, heading straight for them. Tatsuya's instincts kicked in, and before he even realized what was happening, he had already leapt into action. He raced towards the boy and his mother, grabbed the boy, and pulled him to safety just as the truck roared past.
The boy's mother was stunned. "How did you move so fast?" she asked, looking up at Tatsuya in disbelief.
Tatsuya smiled, trying to play it cool. "I just reacted quickly, that's all," he said.
The mother looked at him skeptically but was too relieved to press the issue. "Thank you so much," she said, hugging her son tightly.
Tatsuya watched as they walked away, feeling a sense of pride wash over him. He had used his powers for good, and no one had even noticed. He knew that he couldn't always use his powers in front of others, but it felt good to know that he could help people in secret.
Over the next few weeks, Tatsuya found more and more opportunities to use his powers for good. He helped an old lady cross the street, prevented a car accident, and even saved a cat that was stuck in a tree. Each time, he was fast enough that no one saw him, and he felt like a superhero in disguise.
But even as he helped others, Tatsuya couldn't shake the feeling that he was alone. He wanted to share his powers with others, but he was afraid of what they might think. He didn't know how to balance his newfound abilities with his normal life, and he was starting to feel the weight of it all. But for now, he was content to use his powers for good, even if it was just for a little while longer.
