A row of people stood respectfully outside, listening intently as Old Mr. Jarvis spoke.
With great solemnity, Old Mr. Jarvis introduced her: "Most of you have met Sylvia before—she's visited us in the past. But today, I'd like to make it official. This is Gab's wife, Sylvia, who will be the future mistress of the Jarvis family."
Old Wade was the first to respond, his face full of joy. "Congratulations!"
The others, having recovered from their surprise, quickly echoed him.
"Congratulations!"
...
Sylvia responded with a warm, gracious smile and thanked everyone, appearing composed and approachable. Inside, however, she felt a bit embarrassed—everything had happened so quickly, she hadn't had time to prepare anything, not even a small token to hand out.
Sensing her thoughts, Gabriel gently squeezed her hand and addressed the group with a smile. "Madame has prepared welcome gifts for everyone. Old Wade will see that everyone receives theirs shortly."
Sylvia glanced at Gabriel, slightly startled. Although his face was calm and steady, there was a reassuring certainty in his voice. "This is your home now," he said quietly to her. "It's time to settle in."
Having spent decades in the service of the Jarvis family, Old Wade immediately understood, not needing any cues. He smiled and nodded. "Of course, Gabriel. I'll hand them out to everyone later."
The staff expressed their happiness, offering Sylvia their thanks.
Then, with a smile, Old Mr. Jarvis beckoned Sylvia back into the dining room for lunch.
He hadn't expected the two of them to get married so suddenly, but he'd suspected Sylvia might be joining them today, which was why lunch was especially extravagant this time—a little grander than usual.
Sometimes, the most moving and exhilarating surprises are those that follow after so many twists and turns.
Old Mr. Jarvis was so delighted, he smiled through the entire meal.
After chatting a while longer, Gabriel suggested Old Mr. Jarvis get some rest, and he escorted Sylvia back to Sunrise Villa.
Walking into Sunrise Villa again, Sylvia was struck by how different everything felt now.
She thought back to the New Year holiday, when she and Gabriel hung lanterns together in this very house. It had only been a few months, but the twists and turns since then felt like a lifetime.
Once inside their room, Gabriel closed the door gently. His voice was soft and reassuring. "This is your home too, from now on. If you need to buy anything or want to change something, you have full say here."
Sylvia turned around and wrapped her arms around his firm waist, her expression both charming and bold. "I don’t care where we are. All I need is you, Mr. Carnes."
Gabriel hooked his arm around her waist, lifting her up effortlessly, and carried her to the desk under the window. Bracing his arms on the table, he leaned in, gazing into her eyes. "Nana, from now on, we're equals—as husband and wife. You can ask anything of me."
Sylvia draped her arms around his neck. Her long, wavy hair spilled down, gleaming in the afternoon sunlight. Her features were delicate and striking, crimson lips beautifully curved, her face radiant with a soft glow.
"Really, I have no requests at all."

As the plot thicken. Adrian is done for and he can't try to control Norah, so he'd probably tattle to Janice who's gone for two weeks. Thank you soooo much for the updates....
