My sister never calls me brother.

"Stop! Don't argue!" Song Mingyuan told the two to stop, saying, "Let's think about how to resolve this case first. What ideas do you two have?"

Song Mingyuan still cares a lot about his club.

"Why don't we just let Liu Yue spend more time with her sister?" Zhou Han said.

"This is probably very difficult..." Miyazaki Airi thought for a moment.

"Why?" Zhou Han asked, puzzled. "What's so difficult about spending time with family?"

“Because Liu Yue values ​​her music more than her sister,” Miyazaki Airi pondered.

"Why are you so sure?" Zhou Han frowned. In his subconscious, the club was just a group of people with similar interests who played together. How could it possibly go beyond family ties?

“Liu Yue knew her sister was having problems lately, but she still dumped her sister's issues on us and went back to the guitar club.” Miyazaki Airi paused. “Isn’t that obvious?”

Zhou Han opened her mouth, but couldn't say a word.

Chapter Twenty-One: The Incident Three Years Ago

Lin Nianwei sat in her father's car, resting her chin on her hand and looking out the window.

"Did something happen at school today? You seem preoccupied." Lin's father glanced at Lin Nianwei in the rearview mirror.

"It's nothing," Lin Nianwei said calmly.

"Is that so..." Seeing his daughter's expression, Lin's father didn't press the matter further.

Making himself look bad to attract attention—this childish tactic wasn't new; his sister had used it too. Lin Nianwei recalled things from her childhood—

"Lin Nianwei, she really is here!" Zhou Han grinned, showing his teeth.

A girl who looked younger than Zhou Han stood behind him, clutching his clothes tightly and staring at Lin Nianwei with hostility.

"Who is she?" Lin Nianwei asked curiously.

“She’s my sister! Her name is Zhou Qiqi.” Zhou Han introduced her enthusiastically, and said with a wry smile, “My parents aren’t home today. She throws a tantrum when I come out to play by myself, so I have to bring her along.”

"Really? It's more fun with lots of people." Lin Nianwei smiled.

Zhou Qiqi grabbed Zhou Han's hand and bit it.

"Ouch!" Zhou Han winced as she was bitten. "What are you doing?!"

"You idiot brother! I already said I'm tired! Hurry up and carry me!" Zhou Qiqi said angrily.

"We haven't walked that far! Why are you being so dramatic?" Zhou Han said, annoyed.

"I don't care! If you don't carry me, I'll tell Mom and Dad that you're abusing me!" Zhou Qiqi raised her little fist.

Zhou Han's face darkened, and she squatted down. "Alright! Alright! I give up! Come on up..."

Zhou Qiqi was as happy as a koala, clinging to Zhou Han.

Zhou Han glanced at Zhou Qiqi's bare feet, which were wrapped around her waist and covered in mud, and couldn't help but feel a headache coming on. "Where are your shoes?!"

“I fell off while walking…” Zhou Qiqi said casually.

"If you dropped it, couldn't you pick it up and put it on?" Zhou Han was furious.

“I don’t want to bend over,” Zhou Qiqi said, offering a bizarre explanation. “I wouldn’t carry you even if you asked me to, so I had to walk here barefoot.”

"Don't try to pin this on me." Zhou Han was exasperated. "Where did your shoe fall? Stay here for a bit, I'll go get it for you."

“We went to pick it up together on the way there,” Zhou Qiqi said.

"Are you sick? I went to pick up your shoes, and I had to carry you on my back?" Zhou Han was furious.

"I don't care! I don't care!" Zhou Qiqi threw a tantrum on Zhou Han's back. "If you don't carry me, I'll tell Mom and Dad that you brought me out to play and then deliberately threw my shoes away! You'd better get a beating when you get home!"

"Go away! Go away, okay!" Zhou Han's face fell, thinking to herself, "My sister always uses our parents to pressure me."

"Giddy up! Hurry up!" Zhou Qiqi's laughter was like a wind chime, and she seemed very happy.

Lin Nianwei stared at the brother and sister for a long time, feeling like she couldn't get a word in edgewise.

After a while, Zhou Han returned carrying her younger sister, who was wearing shoes. She thought she could finally breathe a sigh of relief.

“Brother, I’m hungry. I’m going to buy something and I’ll wait for you here,” Zhou Qiqi said.

"Are you ever going to stop?" Zhou Han didn't know what expression to wear when facing her younger sister.

"I don't care! I don't care!" Zhou Qiqi kicked her shoes high into the air.

"Alright! I know you're up to your old tricks, aren't you going to tell Mom and Dad again?" Zhou Han frowned.

"Yes! You have a problem with that?" Zhou Qiqi's expression was unfriendly.

"Yes!" Zhou Han shouted with great pride.

"Hmm?" Zhou Qiqi's face darkened.

"My opinion is... what would you like to eat?" Zhou Han changed the subject.

"Let's go buy a cake," Zhou Qiqi said with a smile.

Zhou Han left, sulking.

Only Lin Nianwei and Zhou Qiqi remained.

“This young lady,” Zhou Qiqi said.

"What is it?" Lin Nianwei asked, looking at her book.

"Could you stay away from my brother?" Zhou Qiqi smiled.

"Why?" Lin Nianwei looked at her calmly.

“Because…” Zhou Qiqi said with a completely innocent smile, “I really dislike you.”

Lin Nianwei, on the bus, snapped out of her reverie, rubbed her temples, and wondered inexplicably why she was thinking about her sister at this moment...

Back home, Zhou Han couldn't understand why Liu Yue valued music more than her younger sister. It didn't make sense in any way. Even if music was a dream, it didn't have to be like this!

So, in order to find out, he has already decided to steal other people's privacy.

"Little Fatty Girl".

"Don't call me chubby girl! I don't want to correct you anymore!" The phone flashed, and Elizabeth's image appeared on the screen.

"Then what should I call you? **?" Zhou Han frowned.

"**You're kidding me!**" Elizabeth rolled her eyes, then thought for a moment, "How about you call me Little Elizabeth?"

"Xiao Yi?" Zhou Han thought for a moment, "Whatever you want."

"What do you want this time?" Elizabeth asked haughtily, arms crossed.

"Could you help me look up information about Liu Yue and her sister?" Zhou Han asked.

"Forget about those erotic images, I can't show them to you." Elizabeth shrugged.

"Am I really that despicable in your eyes?" Zhou Han asked, puzzled.

“Yes! It’s really disgusting.” Elizabeth nodded seriously.

Zhou Han's face darkened. He hadn't expected Elizabeth to show him no respect whatsoever. He pulled a hammer from under the table and said, "I've decided to execute you!"

"No, no, no!" Elizabeth waved her hands repeatedly. "That wicked master isn't filthy at all! He's righteous, upright, and blessed with good fortune. He despises all lewd behavior and is a living example of righteousness!!!"

“I like honest and meticulous people like you…” Zhou Han silently put down the hammer.

Elizabeth breathed a sigh of relief and wiped her sweat.

"I need serious information, not pornographic images," Zhou Han said seriously.

"You're suddenly so serious, it's a little hard for me to accept~" Elizabeth was embarrassed, thinking that there must be something wrong with Zhou Han's brain to talk about serious things.

"I'm begging you, please?" Zhou Han said helplessly.

"Alright, it's rare for you to ask me to do something serious." Elizabeth closed her eyes, and a torrent of azure data appeared behind her, her white ballet dress fluttering even without wind.

Within seconds, Elizabeth opened her eyes, proudly tossed her silver hair, and said, "I'm done investigating."

"Read it to me," Zhou Han said happily, surprised that the search was finished so quickly.

"You should see for yourself!" Elizabeth snapped her fingers, and her phone emitted several beams of light, forming a holographic projection on which most of the information about Liu Yue and her sister was displayed.

Zhou Han looked at it carefully—

The parents of Liu Yue and her sister work in other places all year round. They once sent the two sisters to live with relatives, but not long after, for some unknown reason, the two sisters returned to their own home and lived on the living expenses sent by their parents every month.

The sisters were unaware that they had moved out of their relatives' house. To this day, Liu Yue's parents still believe that their children are living with relatives...

Zhou Han sighed with regret because he himself was almost sent to live with relatives after his parents' divorce. But the feeling of being dependent on others was terrible, so Zhou Han refused to go no matter what. He would rather eat instant noodles every day than live a better life with his relatives.

It wasn't that Zhou Han was stubborn, but rather that she refused to admit she didn't have a home. Even if she were all alone at home, it would be more comfortable than living under someone else's roof.

Zhou Han could more or less understand why Liu Yue moved out of her relatives' house without telling her parents, but if she moved out, why did she bring her younger sister with her? Obviously, her relatives' house could provide better care, right? Besides, Liu Yue's younger sister was still young.

Isn't it every older brother or sister's duty to make their younger sister's life better? Zhou Han couldn't quite understand this, but a familiar figure flashed through his mind... his own younger sister, Zhou Qiqi.

When they were little, Zhou Han would always run off to play, and Zhou Qiqi would always stick to him desperately, which gave Zhou Han a lot of headaches.

I remember once, Zhou Qiqi endured the pain of a fever but still insisted on going out to play with Zhou Han, and as a result, her fever got even worse when they got back.

Zhou Han didn't quite understand her younger sister's persistence.

But Zhou Qiqi said angrily, "Dad, Mom isn't home, and you're not home either, so I don't want to stay here!"

At that moment, Zhou Han's blockhead had a sudden realization: home is not a house, but being with loved ones.

Zhou Han patted her head, thinking to herself, it seems that it wasn't Liu Yue who took her younger sister away, but rather that her younger sister Liu Qing insisted on going with her older sister, just like Zhou Qiqi stubbornly clung to her.

After reading the sisters' information, Zhou Han rubbed his forehead, lost in thought. Now, combining the information he had, he roughly understood the sequence of events—

The Liu sisters were not happy living with their relatives. They moved out and lived on their own without telling their parents. Recently, Liu Yue has been busy with rehearsals for a new piece for her guitar club, which has made her neglect her younger sister who is home alone. That's why she did not hesitate to act like a naughty child in order to get more attention from her older sister.

"It's the same result as Lin Nianwei predicted..." Zhou Han sighed to himself, but there was another question that bothered him, which was what Miyazaki Airi had said—

"She values ​​her music more than her sister."

Although she didn't want to admit it, Liu Yue's actions perfectly matched Miyazaki Airi's words.

“You wicked master, I’ve discovered something interesting,” Elizabeth interrupted Zhou Han’s thoughts.

"What?" Zhou Han looked down at her phone.

Elizabeth's hand slid gently, and a surveillance video appeared before Zhou Han's eyes. The video was from three years ago, during Liu Yue's junior high school years—
