Bittersweet Love: A Demon Slayer Modern AU".

Chapter 1

Chance Encounters

Nezuko Kamado walked down the bustling streets of Tokyo, her heart racing with anticipation. She had just moved to the city from the countryside, and she was excited to start a new life. As she made her way through the crowds, she couldn't help but feel a little overwhelmed by the tall buildings and flashing lights.

Suddenly, she bumped into someone and stumbled backwards. She looked up to see a tall, lanky boy with messy blonde hair staring down at her.

"Hey, watch where you're going!" he exclaimed.

"I'm sorry," Nezuko replied, bowing deeply. "I wasn't paying attention."

The boy's expression softened. "No worries. Are you new here?"

Nezuko nodded. "Yes, I just moved here from the countryside."

The boy grinned. "Well, welcome to the big city! I'm Zenitsu Agatsuma, by the way."

Nezuko smiled back. "I'm Nezuko Kamado."

They chatted for a few more minutes before parting ways, but Nezuko couldn't stop thinking about Zenitsu. There was something about him that drew her in, something she couldn't quite put her finger on.

Over the next few weeks, Nezuko and Zenitsu kept running into each other. They'd bump into each other on the street, or they'd end up at the same coffee shop or bookstore. They started chatting more and more, and Nezuko found herself looking forward to seeing him every day.

One day, they were walking through a park when it started to rain. They took shelter under a tree, but they were still getting soaked.

"Here," Zenitsu said, taking off his jacket and holding it out to Nezuko. "You can wear this."

Nezuko protested, but Zenitsu insisted. "I'll be fine," he said with a grin. "I've got tough skin."

They continued walking through the rain, huddled under Zenitsu's jacket. Nezuko couldn't believe how kind he was, how willing he was to put himself in discomfort just to make her comfortable.

As they walked, Nezuko felt her heart start to race. She couldn't deny it any longer: she was starting to fall for Zenitsu.

But she didn't know if he felt the same way. They had never talked about anything romantic, and she didn't want to ruin their friendship by confessing her feelings.

As they parted ways that day, Nezuko found herself replaying every moment of their encounters in her mind. She didn't know what the future held, but she knew one thing for sure: she was glad she had met Zenitsu.

As the weeks went on, Nezuko's friendship with Zenitsu continued to blossom. They went on long walks through the city, explored new cafes and restaurants together, and even attended a few concerts.

Zenitsu's friends, Tanjiro and Inosuke, often joined them on their outings. Tanjiro was kind and dependable, always ready with a listening ear or a helping hand. Inosuke, on the other hand, was wild and unpredictable, always seeking out new adventures and challenges.
