The Basic Qualities of a Brother-Obsessed Little Sister

Inside the Pope's bedchamber.

The brother and sister were taking turns bathing.

Su Xuan urged her somewhat anxiously:

"Na'er, if you keep dawdling, we're really going to be late."

Gu Yuena was still drying her hair as she sweetly acted coquettish. "It's fine. Even if we're late, Mom will only scold you, not me. Hehehe."

Su Xuan's face darkened slightly. Was this still his sweet little darling of a sister? This little darling had clearly gone bad.

With a dark expression, Su Xuan was just about to scold his mischievous little sister again.

Then he remembered what had just happened.

Gu Yuena's eyes brimmed with tears as she tightly hugged her brother, Su Xuan, and apologized in an extremely aggrieved voice:

"I'm sorry, Brother. This time, I was wrong."

Naturally, Su Xuan could not refuse to forgive his adorable little sister. He patted Gu Yuena's smooth back and comforted her gently:

"It's okay. I'm already very relieved that you understand these things."

Gu Yuena looked at her brother with her violet eyes, sounding aggrieved as she said:

"I'll listen to you from now on, Brother, and I'll work hard to be a good little sister. But you have to promise me a few small requests too."

Su Xuan thought about it. What bad intentions could a little girl her age possibly have? It was already remarkable that she had become sensible. What was wrong with granting a few small requests?

Feeling that his immature little sister had finally become a little more sensible, Su Xuan was greatly comforted and promised grandly:

"No problem. Forget a few small requests—even a few hundred would be fine."

Gu Yuena's violet eyes instantly lit up, and her voice shot up several octaves as she looked into Su Xuan's eyes and asked:

"Really?"

There were only three words, but Gu Yuena's delighted tone could not have been more obvious.

Su Xuan even began to doubt himself. He had always held himself to the standards of a good older brother. Could simply agreeing to a few small requests make her this happy?

Su Xuan felt that he might not have cared enough about his sister in the past, and said with some heartache:

"Of course. Your brother is known as the Young Gentleman of Honesty and Trustworthiness."

Gu Yuena's big eyes curved into crescents as she nearly flew with happiness, laughing as she said:

"Then pinky promise."

Su Xuan promptly went through the pinky-promise ritual.

Gu Yuena then ran to her own private little study. Su Xuan remained where he was, but when Gu Yuena noticed, she ran back and pulled him along.

Once they arrived in the little study, Su Xuan watched as his sister skillfully took out a key, opened a box beside her, and retrieved a very thick notebook.

Gu Yuena was still smiling sweetly.

"Brother, look."

Su Xuan had already seen it. Written across the notebook's cover were ten large words: 10,000 Things a Good Older Brother Must Do.

It was truly difficult to find a single word to describe Su Xuan's expression at that moment. His darkened face was something that could only be understood, not described.

Su Xuan somewhat laboriously accepted the thick notebook. It was filled entirely with handwritten content, and it was hard to imagine how long Gu Yuena had spent writing this "masterpiece."

He casually flipped through its contents. They were all sorts of strange and unusual things, interspersed with Gu Yuena's memories and girlish thoughts. She had probably been writing it as a diary since childhood, framing it as "terms to restrain Brother."

Many of Gu Yuena's girlish thoughts were recorded inside. Even passing thoughts had been written down, such as: Defeat Mom and take Brother back.

Su Xuan's face darkened when he saw that, but there were also some wonderful dreams: climb the tallest mountain in the world with Brother, travel around the world...

There were also romantic, childlike wishes: being able to eat her favorite milk candies every day.

Of course, the largest number of entries were demands specifically aimed at her brother: Brother must never be fierce with his little sister, must not bully his little sister, must comfort her immediately whenever she cried, had to spend time with her every day, and had to tell her bedtime stories forever...

Su Xuan realized that, as a lifelong single dog, his thinking was still not sensitive or delicate enough compared to a girl's thoughts. The methods he had learned from the sacred tome of romance from his previous life were not necessarily always right. He was not a saint and could not account for everything, yet he had been extremely confident, believing himself to be a flawless good older brother and that his little sister was naturally the happiest in the world. He had never communicated with his sister, relying entirely on his own assumptions.

Su Xuan closed this "masterpiece" and looked apologetically at the expectant Gu Yuena before smiling helplessly.

"Brother already said it. Brother's nickname is the Young Gentleman of Honesty and Reliability."

"Yay yay yay! Woohoo! Woohoo! Woohoo!!!"

Gu Yuena jumped up excitedly and stuck herself to her brother like an accessory.

When Su Xuan recalled it carefully, yes, he had not seen wrong. On the first page of the notebook, Gu Yuena had written in bold: No matter what happens, Na'er must always be with Brother.

This old brother's heart warmed so much it felt ready to burst, and his blood began to boil.

Su Xuan felt that he could dance naked in the Arctic just for those words.

Of course, he did not know that Gu Yuena's deepest wish would never be written down, nor would she tell it to anyone.

The true first page of that notebook read: Hold an unprecedentedly grand wedding with Brother Su Xuan, and have Brother Su Xuan stay by Na'er's side for the rest of his life.

Gu Yuena thought, Brother still doesn't know we aren't biological siblings, does he? But I know. Hehe. Tonight, after Brother undergoes Martial Soul Awakening, he'll probably remember what happened when we were little. Then he'll understand that Na'er isn't his little sister. Na'er is his childhood sweetheart, who grew up with him. Gu Yuena secretly indulged in her little thoughts for so long in the bathroom that she exceeded her allotted time and was urged by Su Xuan.

Gu Yuena acted coquettishly.

"Aiya, Brother, wait for me just a little longer. Just a little while."

Su Xuan had a headache. Who did she think was responsible for delaying the Martial Soul Awakening that had originally been scheduled for the afternoon until now? Wasn't it because of her? And now they were about to be late again. Su Xuan was so angry his liver hurt.

Just as he was about to say a few more words, he remembered the restriction he had placed upon himself—the heartless clauses in 10,000 Things a Good Older Brother Must Do, compiled by brother-obsessed Gu Yuena, hereafter referred to as 10,000 Things—one of which was: Do not bully your little sister, and do not be fierce with your little sister.

He could only give up.

By the way, Su Xuan was not the kind of older brother who spoiled his sister without reason. He had made three rules with his sister.

First: overly unreasonable requests could not be accepted.

Second: some things, such as traveling, had to wait for an appropriate time.

Third: other than that, everything could be fulfilled.

Su Xuan waited in boredom.

Gu Yuena had finished dressing up and emerged looking radiant.

A white shirt paired with a short black skirt, black thigh-high socks, and little black leather shoes made her look youthful and beautiful.

Su Xuan, meanwhile, still wore a casual white shirt and black dress pants, which accentuated his tall, straight figure.

Gu Yuena skillfully hooked her arm through her brother's and shouted:

"Let's go!"

Recently, there was a big brother in the group whose book had been doing rather poorly, but a big shot directly gave him a Silver Alliance. He reached one hundred thousand bookmarks overnight. So jealous, so jealous, so jealous.
