Here is a corrected and polished version of your scene. I've improved grammar, punctuation, clarity, and some phrasing to make the dialogue and descriptions flow more naturally, while keeping your original voice and tone intact:
"We're here," said Paul with a smile, pointing toward three people standing nearby. One was a man in his mid 20's with dark hair and bright brown eyes, dressed in a dark formal suit and white gloves. The second was a woman in her late 40s, with dark hair and brown eyes, wearing a maid's uniform. The third was a tall man in a training outfit, a cross-shaped earring in his left ear.
"Hello, Miss Ana. I'm Sebastian—head butler, and Master Paul's advisor," said the man in the suit.
"Best friend as well," Paul added with a grin.
"It's a pleasure to see you again, Sebastian."
"Likewise, Miss Ana."
Ana turned her attention to the woman.
"I'm Lucy, the head maid. It's a pleasure to meet you, Miss Ana," she said, though her tone was tinged with disapproval.
"Yes, ma'am Lucy. I'll be in your care," Ana replied with a warm smile.
Then, she looked to the last man.
"I'm Roger, Master Paul's knight companion... pleasure," he said with a yawn.
"Likewise, Enlightened Roger," Ana said politely.
He gave a small nod.
"Now, there's somewhere I want to take you," said Paul, excitement in his voice.
"Where?"
"A restaurant. An old colleague of mine just opened it."
"Oh, okay. May's still sleeping, right?"
"He actually woke up already—he's playing with Rose in the library."
"Alright. I'll get ready and we can go."
They left in a car powered by essence, sitting side by side, enjoying the view.
"You remember our first date?" Paul asked.
"Yes, it was at that old park, right?"
"Yeah... I had fun that day. Can I ask you something?"
"Of course."
"Why did you choose him?"
Ana averted her gaze and answered slowly.
"He made me feel special... he used to cook for me, told me I was beautiful every day, and listened to me."
"I know you had your duties as a knight, and I understood that, but after my mom passed away... I really needed someone there."
"But over time, he changed—not all at once, but little by little. He started to lose interest. He began coming home late..."
"He wasn't even there when May was born."
"I'm sorry," Paul said quietly.
Paul looked out the window, deep in thought, then said,
"I'll do better. I'll treat you better."
"It's okay," Ana said, gently cupping his cheek. "You're already doing more than enough."
She leaned in and kissed him.
"We're here, Master Paul," the driver announced.
They arrived at a restaurant perched on a high peak overlooking the city. Ana's eyes widened as they entered.
The restaurant had mostly two-person tables facing a reflecting pool, beyond which the city stretched into the sunset. The space was adorned with European-style paintings and furniture. A pianist played softly in the corner, accompanying a singer performing a romantic ballad.
"This looks really expensive..."
"Don't worry. My friend gave me a discount."
"Still..."
They were guided to a table for two by a smiling hostess.
"What will the lovely couple be having tonight?" she asked.
"I'll have the steak," Paul said.
"Hmmm… I'll get the same," Ana replied, a little embarrassed.
"And to drink?"
"Wine, please."
"Anything else?"
"No, that's all. Thank you," Ana said.
"Alright, I'll bring it out once it's ready. Sir, Ma'am," the hostess replied before walking away.
"So how do you want to do things?" Paul asked, smiling warmly.
"However you want. Tell me your plans," she added.
"Well, I'm getting a promotion soon. I'm officially a Master."
"So that's why they were calling you 'Master' earlier."
"Yeah. I'm hoping to keep training and eventually reach Grandmaster rank."
"You were always so talented with a sword," Ana said. "You look like a completely different person when you train."
"Really?"
"Yes. You get so serious and focused."
Paul chuckled softly.
Before he could respond, the server returned with their meals and wine.
"Here you go. Enjoy," she said with a smile.
They began to eat. After a few moments, Paul looked up.
"And... I want to get married too."
Ana looked at him, smiled, and replied,
"Let's do it."
"Also, let's find a tutor for May," Paul added with a grin.
"Really? I'd love that."
"Rose said he loves books."
"Yes, she told me too."
"What about his father?"
"I gave a letter to Sue for him. She said he seemed... indifferent."
"Does he not care for his son?"
"I don't think he does..."
Paul took her hand.
"Then I don't want you seeing him anymore. I'll take care of you and May from now on."
"Thank you," Ana said softly, her smile warm and sincere.
