The richest man's parents were kidnapped, and his adorable son captivated the entire family.

Lu Rongsheng was stunned when she saw Gu Shiyu appear.

Lu Rongsheng narrowed her eyes and shook the photo in her hand. "By the way, Gu Shiyu, you have a new little sister now? I saw you made some rose cakes at home yesterday. Such exquisite and beautiful pastries, did you really make them yourself?"

Gu Shiyu snorted coldly and ignored him.

Lu Rongsheng wisely kept quiet.

He's just being sarcastic and has forgotten how arrogant that bastard is.

Lu Rongsheng exuded confidence and composure as always, while Gu Shiyu maintained a calm yet sharp demeanor.

The two stood face to face, the air thick with tension.

"Hey Gu Shiyu! You're finally back. Ever since you left, I've gotten first place in every exam without a doubt. It's been so much fun..."

Gu Shiyu snorted coldly.

"I came back because I didn't want to see you so smug about being in first place."

Lu Rongsheng suppressed her smile slightly and patted Gu Shiyu on the shoulder.

"Then don't mess up today's big test, give me a good opponent."

"You're the one who should fail the exam and embarrass yourself."

Gu Shiyu raised his hand and slapped his hand away, then said arrogantly.

The classroom was silent, and all the students were secretly looking forward to this battle of academic excellence.

Both of them are top students, and their total scores in each exam differ by only one or two points...

"Our arch-nemesis has met again, how exciting!"

"I heard this test is rated ten stars in difficulty. Gu Shiyu hasn't been to school for a month, so this will be quite challenging for him."

"There's something good to watch."

Lu Rongsheng's lips curled up slightly, his eyes carrying a hint of barely perceptible provocation.

"Gu Shiyu, how about we make a bet today?"

Gu Shiyu raised an eyebrow and gave a cold smile. "What do you want to bet on?"

Lu Rongsheng took out a photo from his schoolbag; it was a picture of 'Mengmeng' that he had taken at home.

He waved the photo around, deliberately showing it to Gu Shiyu.

"Let's bet on the score of this big exam. If you can't beat me, you'll have to admit that my little sister is the cutest."

Gu Shiyu stared at the photo, a disdainful smirk playing on his lips.

"Are you that confident? Humph, if I win, you'll have to post on your WeChat Moments admitting that my sister, Gu Shiyu's sister, is the cutest."

Lu Rongsheng's smile deepened, "Alright, it's settled then. But you haven't studied for a month, so don't deny it if you lose."

Gu Shiyu scoffed, "You should worry more about yourself."

The surrounding classmates, watching the exchange, immediately started to jeer.

"Gu Shiyu really dared to accept that, considering he took a month off from school!"

"Lu Rongsheng actually used his most beloved younger sister to make a bet."

"My goodness, those two have never stopped competing, and this time they've even added their younger sister to the mix. They're really going all out."

The exam bell rang, and a tense atmosphere filled the entire examination room.

Gu Shiyu, however, presented a completely different picture of composure.

The butterflies fluttered around him gracefully, sometimes landing on his shoulder, sometimes hovering beside his hand.

Whenever he was tired, the fairy butterfly would shimmer with a faint light, bringing a refreshing feeling and making his mind sharper and more focused.

When the fairy butterfly grew tired, it quietly landed on his chest and transformed into a glittering brooch.

Gu Shiyu would occasionally look down at it and think of Mengmeng, which warmed his heart.

In the evening, while waiting for the scores.

A group of girls surrounded Gu Shiyu, marveling at the small butterfly on his chest that shimmered with a faint light.

"Gu Shiyu, this butterfly is so beautiful!"

A girl asked with sparkling eyes, "Where did you buy this? I want one too!"

Gu Shiyu looked down at the spirit butterfly nestled against his chest, his gaze softening slightly.

"This was a gift from my sister."

His tone was tinged with doting affection, without him even realizing it.

The girls around immediately exclaimed, "Wow, I never expected Gu Shiyu to be such a siscon!"

"I used to think he was a cool and aloof school heartthrob, but I never expected him to have such a gentle side."

Gu Shiyu felt somewhat uncomfortable listening to these words.

Just as they were about to chase away the noisy female students, the butterfly suddenly flapped its wings a few times.

Tiny rays of light scattered like sparkling stars, reflecting on the faces of several female students.

Those rays of light carried a fresh and natural aura, instantly making the surrounding air incredibly refreshing.

One of the girls, who had a faint scar on her face, subconsciously touched her face.

She was startled; the skin her fingers touched was smooth and flawless, as if the hideous scar had never existed.

A look of shock flashed in her eyes. She quickly took out her mirror and looked at herself, then cried out in surprise.

"My scars are gone! Oh my god! They're really gone!"

Another female classmate next to her always had dry and itchy eyes, but at this moment, she felt an unprecedented coolness and comfort in her eyes.

She blinked involuntarily, her eyes filled with joy.

"My eyes don't feel dry anymore, it's amazing!"

Another female student, who was suffering from headaches, also felt the refreshing scent brought by the butterfly.

She rubbed her forehead, looking much more relaxed.

"My headache is actually gone... Does this butterfly really have magic power?"

The female students around them exchanged glances, then a glint of madness flashed in their eyes.

They immediately surrounded Gu Shiyu.

"Gu Shiyu, your butterfly is amazing! Can you give me one?"

"Gu Shiyu, please sell me one! I can offer you a high price!"

"Please, I can exchange it for shares in my dad's company. I really need it!"

These female classmates are no ordinary people. Some are daughters of financial tycoons, some are daughters of deputy mayors, some are noblewomen from top financial families, and there is even a niece of a foreign president...

They were deeply attracted by the magical healing power of the fairy butterfly.

They all offered high prices, hoping to get one from Gu Shiyu.

Faced with their eager gazes and tempting offers, Gu Shiyu merely raised an eyebrow slightly, maintaining his aloof demeanor.

"No, this butterfly was a gift from my sister, there's no room for negotiation."

Even surrounded by so many noble young ladies, he remained calm and composed.

The possessiveness in their hearts is also secretly at play.

He would never exchange Mengmeng's kindness for anything, nor did he want these spirit butterflies to be casually used for showing off.

Just then, Lu Rongsheng walked in with two report cards in his hand and a complicated expression on his face.

The classroom fell silent instantly, and everyone's eyes were focused on Lu Rongsheng's hand.

Lu Rongsheng took a deep breath and walked up to Gu Shiyu.

"Gu Shiyu, you win."

His voice was filled with regret and admiration, "You scored five points higher than me this time... I'm convinced!"

Gu Shiyu's eyes flickered slightly.

"Hmph, it's good to know."

He raised his hand to straighten the collar of his school uniform. Although he was deliberately aloof, his ears were slightly red.

Lu Rongsheng sighed, "Send me a picture of your sister. I'll keep my bet and post it on my WeChat Moments to praise her."

Gu Shiyu frowned. "I have to ask her first before I can send her the photos. Besides... I haven't even had a chance to take a picture of her yet."

Lu Rongsheng was somewhat surprised upon hearing this.

"You like your sister so much, why didn't you take any pictures of her?"

"Perhaps... there's a saying that's true: we're never in time to record our happiness."

After Gu Shiyu finished speaking, he was stunned for a moment, and found the words to be incredibly apt.

From the moment Mengmeng came to the Gu family, he has been immersed in the time he spends with her.

Surprisingly, I never thought of using my phone to record these beautiful moments.

Seeing his unusual expression, Lu Rongsheng felt a surge of curiosity about the mysterious "sister".

Lu Rongsheng's gaze fell on the spirit butterfly on Gu Shiyu's chest.

"This glowing butterfly is really special. You said it was a gift from your sister?"

Upon hearing this, Gu Shiyu felt a surge of tenderness in his heart, and his tone softened slightly.

"Yes. She is indeed very special."

Lu Rongsheng couldn't help but be curious.

He thought of the little girl he had seen in the Gu family's car that morning.

Is she Gu Shiyu's new younger sister?

But her appearance...

"You said your sister is so cute, can I meet her?"

Gu Shiyu raised his eyebrows slightly, a hint of arrogance on his lips.

"My sister isn't someone just anyone can meet."

Lu Rongsheng frowned, unwilling to give up, and asked, "How can I see her?"

Gu Shiyu snorted coldly, his refusal was quite clear.

Lu Rongsheng awkwardly touched his nose and was about to walk away when he felt a light flapping sound beside him.

Looking down, he saw that it was Gu Shiyu's spirit butterfly that had flown over and was dancing around him in circles.
