The morning sunlight filtered through the windows of Emily Cooper's apartment, casting a warm glow over the room. Harlan Bishop stretched lazily, savoring the moment before his Parisian adventure continued. Mindy Chen, already up and sipping coffee, glanced over at him with a smile.

"Ready for another day of excitement?" she asked.

Harlan grinned. "Absolutely. Where are we headed today?"

Emily, emerging from her room, answered with enthusiasm. "We're meeting Camille at the Hôtel des Invalides. It's going to be amazing."

After getting ready, the trio hailed an Uber and soon arrived at the grand entrance of the Hôtel des Invalides. The building's majestic architecture and rich history left them in awe.

"Wow, this place is incredible," Harlan marveled as they stepped out of the car.

Emily nodded. "It really is. I've always wanted to explore it more."

As they entered the courtyard, they spotted Camille waving at them with a bright smile. She had someone with her, a beautiful woman with dark hair and an elegant demeanor.

"Hey, you guys!" Camille called out. "I'm so glad you could make it. This is my girlfriend, Sofia Sideris."

Sofia extended her hand warmly. "It's a pleasure to meet you all. Camille has told me so much about you."

After exchanging pleasantries, Camille began their tour of the Hôtel des Invalides, starting with a brief history lesson. "The Hôtel des Invalides was originally built as a hospital and retirement home for war veterans. It's also the burial site for some of France's war heroes, including Napoleon Bonaparte."

As they continued to explore the stunning grounds and historic buildings, their tour was abruptly interrupted when Emily spotted a familiar face in the distance.

"Oh no, that's Alfie," Emily whispered, her expression tense.

Harlan glanced at her curiously. "Who's Alfie?"

Emily sighed. "He's my ex-boyfriend. We broke up because, well, it's a long story. Basically, at Camille's wedding, I realized I still had feelings for Gabriel. Alfie found out and didn't want to be anyone's second choice."

Harlan frowned. "Second choice?"

Emily nodded, her voice soft. "He didn't want to be with someone who had stronger feelings for someone else."

Their conversation was cut short when Alfie, noticing them, began to approach. His expression was a mix of surprise and anger.

"Emily," he said curtly. "We need to talk."

Emily took a deep breath. "Alfie, we've been through this. We need to work things out."

Alfie's voice rose in frustration. "Work things out? You're still hung up on Gabriel! And who's this guy?" He pointed at Harlan.

Harlan extended a hand. "Hi, I'm Harlan."

Alfie ignored him and turned back to Emily, his tone dismissive. "You need to sort out your feelings, Emily. This isn't fair to anyone."

Harlan, trying to keep the peace, spoke up. "Alfie, maybe we can keep our voices down and talk about this calmly."

Alfie glared at him. "Stay out of this. This is between me and Emily."

Camille and Mindy, hearing the commotion, approached quickly. "What's going on?" Camille asked.

Emily sighed. "Alfie and I are just having a disagreement. He's upset about the past."

Alfie crossed his arms. "Upset? That's an understatement."

Mindy stepped in, her tone firm. "Alfie, I think it's best if you leave. We're trying to have a peaceful day here."

Alfie scoffed. "Fine. But before I go, do you know Ingrid Corey? We're dating now."

There was a moment of stunned silence before Alfie added, "Oh, and Emily, you might want to check your Vitamin B3 levels. Ingrid seems to think you're lacking."

As Alfie stormed off, Emily stared after him, bewildered. "First Ingrid, now Alfie? What is with this Vitamin B3 obsession?"

Harlan shook his head, chuckling. "Paris is full of surprises."

Camille sighed. "Let's not let this ruin our day. We still have so much to see."

With that, they resumed their tour, determined to enjoy the rest of their day despite the unexpected drama. As they explored the Hôtel des Invalides, the grandeur of the historic site helped them forget the bizarre encounters, at least for a while.

Later, as they sat down for a quiet lunch in a nearby café, Emily raised her glass. "Here's to adventures, friends, and the craziness that comes with them."

Harlan and Mindy clinked their glasses with hers, smiling. "To Paris," Harlan said, feeling grateful for the new experiences and the wonderful friends by his side.
