Here's the polished, humanized, and grammatically corrected version of your passage, with the main characters changed as requested (Ethan and Mia). Flow and emotion have also been enhanced:
---
Ethan stepped out of the yard and leaned casually against the gate, chatting with Mia.
"What exactly are you up to in there?" she asked, narrowing her eyes in mock suspicion. "Do you really love farming that much?"
Peeking past him into the courtyard, she saw only neatly growing rows of vegetables basking in the morning sun. She puffed up her cheeks and muttered, "I'm actually kind of mad, you know. Am I not pretty enough? Even though you have such a gorgeous girlfriend, you never really take me on proper dates."
Ethan gave her a sideways look. "Don't I go shopping with you? Ride with you on your scooter every morning?"
Mia pouted, clearly unconvinced. "That doesn't count! You only spend an hour a day with me, then you're back to farming all day long." A faint blush spread across her round cheeks. Her voice softened, almost shy. "I've been studying how to be a good girlfriend, you know. I'm serious about this relationship. Is it that I'm just… not charming enough?"
Ethan chuckled. "What have you been studying? Girlfriend manuals?"
"Hey! Don't laugh at me!" she warned, half-embarrassed, half-flustered. "Laugh again and I'll hit you. I'm trying, okay? I've never dated anyone seriously before! And now I only have four days of summer break left before I have to go back to school..."
When she handed him the lunch box, Ethan went quiet for a moment.
Without realizing it, summer was already ending. The chaos of managing the sandbox and wrangling his idiotic players had consumed all his attention. Now, the reality of parting hit him.
Truth be told, he'd grown used to it—these quiet countryside days, the warm meals, the sweet companionship. Mia's feelings were obvious. She had come to him at the lowest point of his life, offering love and comfort when he had little left to give.
"So… no more food deliveries after this?" Ethan asked, half-joking, half-sincere.
Mia shot him a glare, then laughed. "Ugh! You're the worst! Is that the only reason you made me your girlfriend? For free meals? Don't worry, once I'm back at school, Auntie Li will take over your meals."
Ethan smiled but then said, more seriously, "Hey… long-distance isn't so bad these days. We have video calls."
"Video calls aren't the same!" Mia protested with mock drama. "It's not real dating! And besides, you're... you're dying! I won't even be able to say goodbye in person..."
Ethan: "..."
Can we stop bringing that up every five minutes?
He opened his mouth to respond but gave up, realizing they were equally terrible at handling emotions.
Instead, he shifted gears. "By the way, have you heard of a game called Spore Evolution?"
Mia blinked. "Nope."
Of course she hadn't. Mia only played cute, relaxing games. Violence made her squeamish. Or so she claimed.
"It's a sandbox game. Super casual, very chill—like Minecraft, but with more freedom. You've played Minecraft before, right?"
"I have!" she nodded eagerly.
Ethan grinned. "Well, this one's even better. It's like a second life—completely immersive. If we both get in, it'll feel like we're really together."
Mia's eyes lit up. "Wait, really? Like actually together? In-game?"
"Yup. There's just one catch: to qualify for a beta tester slot, you have to submit a scientific paper... on evolutionary biology."
"...What?"
Mia stared at him, betrayed. "You said this was a casual game!"
"It is," Ethan said with a straight face. "Don't worry. I'll handle it. Once you're back at school, I'll hire someone to write the thesis for you. All you'll have to do is log in. I'll even buy you a laptop that can handle it. Maybe a $20,000 model?"
Mia squealed. "I love you! You're the best!" She stood on tiptoe, kissed his cheek, then turned beet red and darted off like a startled rabbit. "We can be together again!"
Ethan stood at the gate, hand on his cheek, chuckling to himself. "Girls really can't resist sweet words… and expensive hardware."
But deep down, he was glad. If he couldn't do even this much for her, what kind of Creator was he?
Getting her a beta slot was easy. The real problem? That $20,000 laptop. It'd bring his savings down to $80,000—not ideal. Still, he didn't mind spending it. But he'd need to find a way to make more money soon.
He turned to look at the sandbox in the distance and smiled.
In the future, their dates would be inside that magical little world. They'd walk together, hand in hand, through strange forests and under alien skies, watching the antics of players and the evolution of bizarre creatures.
It was a fantasy world—one he had built, and one he was beginning to share.
Satisfied, Ethan returned to the house with the lunchbox in hand. It was time to get back to work.

Meanwhile, inside the sandbox...
"Genesis?"
The players stood in stunned silence atop the giant notebook, staring at the elegant, hand-written title.
"Why would that word be here?"
"Is this… a hidden quest line?"
A wave of excitement ran through the players.
They had stumbled into something big.
"To think this game had lore all along! I thought it was just a biology sandbox..."
"Guys! This might be a main story cutscene!"
Their excitement boiled over. These were veteran MMO players—they knew when they'd triggered something important.
"This game has a background narrative?!"
"The developers weren't just hardcore—they're literary geniuses too!"
The patchwork crowd of strange creatures—tentacled, winged, clawed—scrambled across the massive page.
"Quick! Turn the page! What else is in this Book of Genesis!?"
With Akina's Speedster leading the charge, they pooled their strength and flipped the next colossal sheet.
"The Dark Age."
The world was plunged into 5,000 years of endless night. The sun vanished; only the moon remained. Nearly all marine life perished—except for a single survivor: the Blue Moongrass, a photosynthetic plant that could absorb moonlight and thrive in the abyss.
"Whoa… is this lore from a past era?"
"Film it! Turn on the recording function! Hurry! The giant could return any second!"
Excitement was turning into frantic panic.
They flipped again.
"The Radiant Age."
The moon set, and the sun rose once more. The world was scorched in golden light. The Blue Moongrass withered, but a descendant, the Violet Herograss, inherited the earth and flourished.
Another turn.
"The Revival Age."
Life exploded. Invertebrates ruled, only to be overtaken by vertebrates. The ocean was a battlefield, and evolution was the weapon.
They barely had time to process it all.
Another flip.
"The Age of Genesis."
The first intelligent species—the Bugapes—built city-states, developed civilization, and waged war against giant beasts. But their cruelty drew the wrath of heaven, and a great flood ended them in the third extinction.
The players were silent.
> There were intelligent beings before us? City-states? A divine flood?
And then came the final page.
"The Age of Magic."
> "In this age, magicians began to flourish, guided by Hermes, the God of Wisdom. He descended from the heavens, taught the Three Witches, and helped them forge the path to immortality. In the year 198 of Babylon, they died—and the world wept for them."
Silence.
Then awe.
A vast and majestic world stretched before them, revealing itself one handwritten word at a time.
The sandbox wasn't just a game.
It was a world with history, myth, sorrow, and legacy.
And they had only just begun to read the first chapter.
