Brother! This is the adoption certificate. I don't want your sister-in-law!

Su Xiao watched her stand there with her head down, holding the old schoolbag with its worn edges in her arms.

Like a little sparrow that has been rained on and dried in the sun, it huddles in a corner, too afraid to fly.

He felt as if a part of his heart, which had been worn cold by the cutthroat competition of the business world in his previous life, had softened.

He walked over and lowered his voice.

"Xu Niannian, listen to me. I'm not a good person, but I'm not so bad as to think you're a disgrace. I'm glad you came today. So don't say those kinds of things again, understand?"

As Xu Niannian listened to his unusually gentle tone, a part of her heart, like tea leaves steeped in warm water, slowly unfurled.

Actually, she's happy as long as this bad guy doesn't yell at her or bully her.

She nodded gently, hugged her schoolbag to her chest, and followed behind him.

Su Xiao had booked a research room in the library in advance, a private room, so she could study peacefully.

The research room was quiet. There was a row of long tables by the window, and sunlight streamed through the blinds, casting golden stripes on the tabletops.

When Xu Niannian sat down, she only sat on the front half of the chair.

His bottom rested lightly on the edge, his back was straight, and his two feet were placed properly on the ground, as if he was afraid of getting the chair dirty.

Su Xiao turned around and saw her like this. She walked over, grabbed her shoulder, and pulled her up, pressing her into the chair.

"Sit tight, the chair is free."

Xu Niannian was pressed back by him, and her little bottom finally sat firmly on the ground.

Su Xiao thought, "I can't let her have any free time. If Xu Daidai has any free time, she'll definitely start overthinking again."

He decisively pulled out his chemistry notebook from his bag, flipped to the topic of ion coexistence that he hadn't finished explaining last time, and pushed it in front of her.

"Teacher Xu, we didn't finish explaining this question last time."

Sure enough, Xu Niannian's expression changed as soon as she saw the question.

The unease I felt earlier gradually faded, replaced by a natural seriousness.

She picked up her pen, pointed to the question, and began to speak softly.

His voice was still so soft. When he got to the key points, he would lightly tap the paper twice with the tip of his pen, then quickly look up at him to make sure he was listening, before lowering his head again to continue speaking.

The two of them studied until the afternoon.

When Su Xiao came out of the library, she felt dizzy, as if someone had pried open her skull and stuffed a bunch of chemical equations into it, and she was even a little unsteady on her feet.

Damn it, if only I had a system! Where's my learning system?

Xu Niannian followed behind him, still carrying her schoolbag, but her complexion was much more natural than in the morning.

The setting sun shone on her face, revealing two shallow dimples on her cheeks, which she herself did not even notice.

Su Xiao glanced back at her, then suddenly remembered something, pulled her backpack to the front, and took out a small cloth bag from it.

"Here, take this."

Xu Niannian took the cloth bag, opened it, and found a cell phone inside.

This Nokia candybar phone has a new casing and a screen protector; it's in much better condition than before.

She paused for a moment, then quickly pushed the phone back.

"No, no..."

"Who said it was a gift for you?"

Su Xiao crossed her arms, her face serious. "This is for you to use. You can call me at night to ask me questions when I'm not around. It's for studying, understand?"

Xu Niannian hesitated for a moment before slowly taking the phone back and holding it in both hands.

"The phone card has been purchased and a year's worth of credit has been deposited."

Su Xiao pointed to her phone, "I'm the first one listed in the contacts. Call me if you need anything."

Xu Niannian had never used a mobile phone before, and she looked down and pressed several buttons before she could open the contacts.

There is only one contact person.

The nickname is not "Su Xiao" or "Brother Su", it's two characters.

husband.

Her face flushed instantly, burning from the base of her neck to her forehead. She looked up pitifully at the screen, unable to speak.

Su Xiao glanced down at the spot she was pointing to, her face expressionless, her tone as serious as if she were reading a physics lab report.

"You can't change this name. It's a default setting on the phone. If you change it, the phone will explode, understand?"

Xu Niannian blinked, then looked down at the two words on the screen, her mouth moving slightly, looking bewildered.

"Do you understand?" Su Xiao frowned, her voice slightly harsher.

Xu Niannian nodded quickly, carefully holding the phone in her hands, her voice simple and honest.

"understood."

Su Xiao took the phone and helped her register a QQ account.

Back then, the mobile QQ app was still in its most rudimentary version, and Su Xiaoguang couldn't stand the sight of it.

Xu Niannian stood on tiptoe beside him, her eyes wide with curiosity as she watched him operate the phone.

She had never owned or used a mobile phone before; she had only seen others use them, so her big eyes were full of curiosity.

"I'll give you a name."

Su Xiao stopped at the nickname field, turned to look at her, and said, "How about 'Unforgettable'?"

Xu Niannian looked up at him, then lowered her head and nodded forcefully.

Su Xiao quickly typed the message, then selected a built-in panda avatar for her, added his own QQ number, and handed the phone back to her.

Xu Niannian held her phone, looking at the only friend in her friend list with a curious expression.

The profile picture is a red dinosaur, which is the system's default color, and the name is "Social Brother Su".

She silently memorized the name.

This is a bad person.

Su Xiao chuckled and sent her a message on his own phone.

Brother Su, a socialite: Little sister, do you have a boyfriend? Can you be my girlfriend?

Xu Niannian looked down at the message that suddenly popped up on the screen, and her face turned red instantly.

She glanced up at Su Xiao furtively, then quickly looked down again.

She seemed to want to reply, her fingers tapping the keyboard several times, but it was all gibberish. She deleted and pressed again, pressed and deleted again.

Su Xiao leaned over and pointed to the nine-key keyboard, teaching her one key at a time.

Xu Niannian is a good student, but she's completely clueless when it comes to electronic devices. Even after being taught for a while, she still couldn't type out a complete sentence.

Su Xiao gave up and waved her hand, telling her to go back and practice on her own.

Xu Niannian looked down at the garbled text input box on her phone and silently made a mental note of it.

……

When Su Xiao got home that evening, she was exhausted.

After taking a shower, I collapsed on the sofa and spent half an hour reviewing my math notes and then half an hour memorizing vocabulary, as Su Wan Ning had instructed.

After completing the entire learning process today, he felt completely drained, and he was about to fall asleep the moment his head hit the pillow.

My phone suddenly chimed.

Someone sent me a message on QQ.

Wu Mengmeng?

This was his first thought.

When I picked it up and looked at it, it wasn't.

It was sent by Xu Niannian.

Unforgettable: I've learned to type.

Su Xiao was stunned for a moment, and her sleepiness was mostly gone.

He leaned against the headboard, a smile unconsciously curving his lips as he typed a reply.

Brother Su from the Social Circle: Who taught you that? You're so amazing.

A while later, another message came.

I can't forget you: I also want to chat with you.
