At evening.

Jiang Shuyi was sitting at the table in the living room, working on problems.

Wen Yao sat quietly beside her, checking her physics exam paper.

After a while, Wen Yao pointed at a question on the paper with her finger, "You got this one wrong."

"Oh."

Jiang Shuyi glanced at Wen Yao's fair neck, with her inky black hair cascading over her shoulders, making her look like a scene from a snow-covered landscape.

"If you get the next question wrong, you'll have to do another paper."

Wen Yao's calm voice echoed in the cold air.

Jiang Shuyi quickly snapped back to attention, her eyes fixed on the paper in front of her.

"Wen Yao, don't you think this paper is a bit too difficult for me? And the homework you assigned today is also double the usual amount."

Wen Yao didn't respond, her expression cold as she flipped through the book in her hands.

"...Wen Yao." Jiang Shuyi called her name pitifully.

Wen Yao abruptly closed her book and looked at Jiang Shuyi with a cold expression.

"Jiang Shuyi, although I don't want to say this, I've been teaching you for so long. Haven't you made any progress?"

"Can't you even solve this one question?"

"I've taught you everything I can, Jiang Shuyi."

"I hope you can achieve some results too."

Wen Yao's tone was icy.

". . ." Jiang Shuyi couldn't help but nod nervously, "Oh, I'm sorry."

So scary.

". . ."

Jiang Shuyi noticed that Wen Yao had deliberately assigned many difficult questions today.

Moreover, usually, even if Jiang Shuyi performed poorly, as long as she didn't make foolish mistakes, Wen Yao would patiently teach her.

But today, she didn't tell her the problem-solving approach, making her seem particularly harsh.

Jiang Shuyi couldn't quite describe how she felt, but she sensed that this was Wen Yao's way of getting back at her.

This was the retaliation for her teasing Wen Yao about 'nesting behavior' yesterday...

Jiang Shuyi lowered her head and silently worked on the problems.

Jiang Shuyi knew that Wen Yao had a strong sense of revenge.

However, Jiang Shuyi felt she didn't mind at all.

—After all, this person beside me may seem like she says nothing on the surface, but she still quietly collects my clothes in private.

—Since she's so cute, I can understand her.

". . ."

Jiang Shuyi found herself shaking her legs for some unknown reason, her mood growing brighter.

Wen Yao glanced at her. "Jiang Shuyi, don't shake your legs while you're working on the problems."

Wen Yao's expression was distant and cold, making her look quite stern.

"...Oh."

Jiang Shuyi blinked and stopped shaking her legs, then continued to work on the problems.

But it wasn't long before she started humming a cheerful tune again.

". . ."

Wen Yao listened to Jiang Shuyi humming a song at some point, not saying a word.

Doo doo doo doo—

The sound of a phone vibrating.

Jiang Shuyi glanced at her phone; it didn't light up.

She then looked at Wen Yao's phone.

Wen Yao's phone screen displayed a string of phone numbers.

Jiang Shuyi paused, as Wen Yao rarely used her phone, and she was curious about who would call her so late.

It should be an urgent call at this hour, but the caller's name was not visible.

Wen Yao crossed her arms and glanced at Jiang Shuyi, then tapped Jiang Shuyi's forehead with her red pen, "Don't get distracted by things around you, focus on your problems."

She walked towards the balcony with her phone.

Jiang Shuyi lowered her head, watching Wen Yao turn her back and walk away to the balcony, then raised her head to look at Wen Yao.

—Who could it be?

Jiang Shuyi perked up her ears.

"Mm, it's me, good evening..."

"Teacher Li."

Wen Yao, standing not far away, quietly called out Teacher Li's name, and Jiang Shuyi buried her head again, continuing to shake her legs and work on the problems.

"Hmm, not yet."

Wen Yao's polite voice answering Li Roujia came from the balcony.

"Hmm, I understand, okay."

"So, I just need to send the documents to you, right?"

"Okay, I got it."

". . ."

It seemed to be the usual trivial matters again.

Jiang Shuyi didn't understand why a class monitor could handle so many things.

Jiang Shuyi watched Wen Yao slowly hang up the phone and then sit back down next to her. For some reason, she recalled that when Teacher Li had called earlier, Wen Yao's phone screen displayed a string of numbers without any notes.

So, why hadn't Wen Yao saved Teacher Li's phone number?

". . ."

Suddenly, Jiang Shuyi felt curious.

She straightened up and secretly glanced at Wen Yao's phone screen, just as Wen Yao happened to open her text messages.

The message inbox was completely empty, not even a single promotional message left, except for one conversation thread.

Jiang Shuyi paused when she saw the message thread labeled with the character 'Jiang.'

The date was from last month when she had texted Wen Yao about going to the library together.

For some reason, Jiang Shuyi suddenly felt her mind was a bit muddled.

". . ." Jiang Shuyi leaned over towards Wen Yao's phone.

"...Are you a giraffe? Sit back down."

Wen Yao lightly tapped Jiang Shuyi's head.

"Wen Yao." Jiang Shuyi rubbed her head where Wen Yao had tapped and subtly leaned closer to her.

"Hmm." Wen Yao quietly continued operating her phone while glancing up. "What's wrong?"

Wen Yao lifted her eyelashes to look at Jiang Shuyi.

Jiang Shuyi pointed to a yellow icon in a corner of Wen Yao's phone. "Can you click on that yellow icon for me?"

Wen Yao glanced at her contact list on the phone and paused for a moment.

"...Why?"

Wen Yao looked at Jiang Shuyi with a neutral expression, her tone revealing no hint of happiness or anger.

"Wen Yao," Jiang Shuyi shook her shoulder, "if you show it to me, I won't bother you all night."

". . ." Wen Yao paused, not replying to Jiang Shuyi.

Jiang Shuyi looked at Wen Yao with anticipation.

After a moment, her expression became somewhat probing.

"Is there something on your phone that I'm not allowed to see?"

"No." Wen Yao answered decisively.

"Then—"

Jiang Shuyi blinked, her face seemingly saying, 'You're hiding something I can't see!'

". . ."

Before long, Wen Yao expressionlessly moved her finger to the icon and tapped it.

The icon opened.

The information belonging to the contacts section expanded all at once.

Compared to Jiang Shuyi's contact list, which was filled with names of all kinds, Wen Yao's contact list had no names logged, not even entries related to her family.

The only note was a single character: 'Jiang.'

". . ."

Jiang Shuyi pressed her lips together, momentarily unsure of what to say about this contact list.

She glanced at Wen Yao and then at the contact list that only had her phone number.

"Have you seen enough?" Wen Yao asked coldly, closing her phone.

"...Yeah, that's enough."

"Do your problems and stop talking nonsense." Wen Yao said as usual.

Jiang Shuyi felt her mood becoming quite complicated.

---

At night.

The sky at the end of December didn't look bright, it was overcast.

Jiang Shuyi turned over in her bed, unable to sleep for some reason.

She tossed and turned, her mind still lingering on Wen Yao's contact list.

She was really curious.

Logically, not having notes would be quite inconvenient.

If she didn't have notes, she wouldn't be able to distinguish between phone numbers except for the ones she was familiar with.

So, not having notes seemed unreasonable for that efficiency-oriented little professor.

—So what could lead Wen Yao to only note down my phone number in her phone?

—Leaving everything else out except for my texts.

"So..."

After thinking of an answer, Jiang Shuyi silently stared at the ceiling, feeling her heart race a bit.

"So, could it be that Wen Yao—"

Her ears grew warm again, and she turned over.......

---

The winter sun shone gently through the window, casting colorful shadows on the ground as it refracted through the glass.

Jiang Shuyi slowly exhaled.

". . ."

Song Jinxi and Zhou Jingtang walked in from outside.

Seeing Jiang Shuyi's appearance, Zhou Jingtang pulled a can of coffee from her pocket and placed it in front of her.

"Miss Yi, did you go steal a cow last night?"

Jiang Shuyi, with dark circles under her eyes, blankly glanced at the two in front of her.

"No," Jiang Shuyi nodded slightly, taking the coffee, "I didn't sleep well last night, I was thinking too much and couldn't sort it out."

She was really curious.

Song Jinxi looked at Jiang Shuyi in disbelief.

To her, Jiang Shuyi's sleep quality was too good, it was the kind that everyone envied.

Zhou Jingtang leaned against her desk and asked, "What are you thinking about?"

". . ." Jiang Shuyi glanced at Zhou Jingtang and thought for a moment before saying:

"There's a person whose phone only has your number saved, and no one else's."

"Why do you think that is?"

". . ."

Song Jinxi looked at Wen Yao with a face full of curiosity and pulled out a chair to sit next to Jiang Shuyi.

Zhou Jingtang pondered for a moment and said, "If no one else is saved, and only I am, doesn't that mean I'm quite special?"

"I think, perhaps in this person's heart, I should be quite important, right?"

"...Right? I—"

Jiang Shuyi sat up a bit straighter, feeling a little shy.

—That's what I think too.

After a few seconds, Zhou Jingtang paused, took out his phone, and continued, 

"Of course, there's another possibility. For example, this person might not make many calls and just happened to save one number."

"After all, for commonly used numbers, you just need to input the beginning digits, but there are some numbers I can't be bothered to remember."

He entered a few digits into his phone. "You see, when I call my mom, I just input the numbers directly, I've never saved a note for her."

"So, it's also possible that to that person, I'm just someone whose number they don't really want to remember."

"Indeed, there are many possibilities, making it hard to analyze..."

Zhou Jingtang casually took back his phone.

Jiang Shuyi looked at Wen Yao, who was reading in the distance, and her expression began to darken.

"Is that so..."

Jiang Shuyi fell silent.

Indeed, Wen Yao usually doesn't contact others much, she probably only calls Li Roujia occasionally.

Just saving her surname doesn't indicate anything, it doesn't express anything.

It might even suggest that she's not familiar with her own phone number.

". . ."

At that moment, Zhou Jingtang's phone suddenly rang. He looked at the caller ID and, without hesitation, answered the call while walking toward the door.

"What are you doing here?"

"Hmm, okay..."

Zhou Jingtang hurriedly walked toward the door.

Song Jinxi called out to him, "Zhou Jingtang, class is about to start."

"I'll be right back, my middle school classmate is here to see me." Zhou Jingtang waved his hand.

"A middle school classmate?" Jiang Shuyi raised her head warily at this mention.

Zhou Jingtang seemed not to hear Jiang Shuyi's question and hurriedly walked toward the door.

"I'll be right over, just wait for me at the entrance for a moment."

"Xiao Jiayu."
