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

Su Xiao sat on the sofa and flipped through the several science and technology newspapers she had bought from the newsstand outside the computer mall.

Electronics Information Weekly, Computerworld, and South China Electronics Market Express.

The dishes were laid out one by one on the coffee table, with the key parts circled with a pen.

Flash memory chip production capacity adjustments, upstream manufacturers' inventory backlog, and a sharp decline in USB flash drive export orders.

Every message points to the same conclusion.

It's the end of October now, and prices are at rock bottom. By mid-November, prices will skyrocket.

Stable.

That's it!

He put down the newspaper, and the vague plan in his mind became clearer and clearer.

Now I can confidently go all in on my USB drive!

I folded the newspaper and put it in the drawer under the coffee table, then looked up at the window.

It was completely dark, and the streetlights cast the shadows of the trees onto the window, swaying gently.

Why isn't Su Wan Ning back yet?

The food on the table is ready.

Three dishes and one soup: sweet and sour pork ribs, scrambled eggs with tomatoes, garlic broccoli, plus a bowl of seaweed and egg drop soup.

The spare ribs were specially selected by him from the market, the scrambled eggs were cooked to the soft-boiled consistency that Su Wan Ning liked, and even the seaweed in the soup was torn into pieces of the right size.

The refrigerator was full of newly bought vegetables, the floor had been mopped, the dust on the coffee table had been wiped off, and even the shoes on the shoe cabinet were neatly arranged.

As he was pondering what he might not have done properly, he heard footsteps in the hallway.

He was so familiar with that rhythm.

The footsteps were neither fast nor slow, nor heavy; they were those of Su Wan Ning.

My dear sister is back!

Su Xiao sprang up from the sofa and took two steps to the door.

The door opened.

Su Wan Ning was dragging a suitcase with one hand and carrying a bulging supermarket plastic bag in the other, looking down to take out her keys.

She was taken aback when she saw the door open by itself. She looked up and saw Su Xiao standing in the doorway with a bright smile on her face.

"Welcome home! You've had a long journey, I've missed you so much! Here, give me your luggage..."

Su Xiao reached out to take her suitcase.

Su Wan Ning was a little embarrassed by his enthusiasm, and her ears turned red, but she quickly regained her usual cold and indifferent expression.

She pushed the suitcase to him, picked up her own bag, and walked into the house, her gaze sweeping over the living room without making a sound.

The floor had been mopped, the shoes on the shoe cabinet were not scattered about, and there were no leftover instant noodle containers piled up on the coffee table.

Her worries before she left, that he would turn the house into a pigsty, now seem unnecessary.

Looking at the dining table again, there were three dishes and a soup, still steaming hot.

Su Wan Ning's lips curled up slightly, but she quickly suppressed it.

No, what am I happy about?

Su Xiao followed in carrying her suitcase, and immediately noticed the bulging plastic bag in her other hand.

The bag is semi-transparent, and you can vaguely see the potato chip packaging and beverage bottle inside.

His eyes lit up: "You even bought me snacks?"

Su Wan Ning's body trembled violently, like a cat whose tail had been stepped on.

She quickly hid the bag behind her back, her face flushed red, and her voice became unnatural: "Who, who bought this for you? This is for my own consumption."

"Oh, I ate it myself."

Su Xiao drew out her words, her smile stretching almost to her ears.

Su Wan Ning felt uncomfortable with his laughter and glared at him fiercely.

How do you explain the "glare" method?

With round eyes and tightly pursed lips, it looked fierce, but also like a kitten whose chin had been scratched and who was trying to act aloof.

Its lethality is zero.

She probably realized that her glare wasn't very intimidating, so she changed the subject and took an envelope out of her pocket and stuffed it into Su Xiao's hand.

"First prize, 1000 yuan, I'll give you 800. I'll keep the rest to buy study materials."

Su Xiao took the envelope, didn't count it, but instead reached out and gently patted her on the head.

"Wow, you're the best in the whole grade. It seems you've inherited all the intelligence genes in the Su family, while your older brother only inherited your handsome and dashing looks."

Su Wan Ning was startled by his pat, reached out to straighten her bangs that had been messed up, lowered her head, and her ear tips started to turn red again.

"Don't touch me, I'm so annoyed. Keep your money safe, don't waste it."

She paused for a moment, then said, "I'm hungry."

"Alright!"

Su Xiao quickly pulled out a chair for her to sit down, and then went around to sit on the opposite side herself.

Su Wan Ning picked up her chopsticks, took a piece of pork rib, chewed it, and her eyes lit up slightly.

He didn't speak, but his chewing speed noticeably increased.

While she was eating, Su Xiao took the initiative to report on her learning progress.

He recounted in detail how many pages of math notes he read on which day, how many words he memorized on which day, and how late he stayed up doing math problems on which day.

Su Wan Ning listened without praising or criticizing, simply nodding slightly and picking up another piece of green vegetable with her chopsticks.

After finishing her meal, Su Xiao cleared the dishes and went to the kitchen to wash them.

The tap was running, and his voice came from the kitchen: "It rained outside for a while, did you get wet? Why don't you take a hot shower first, so you don't catch a cold."

"No."

Su Wan Ning sat on the sofa, picked up the remote and turned on the TV. "I didn't get wet. It just started raining heavily when I got to the supermarket entrance."

She suddenly remembered something, looked up from the TV, and asked, "Where's the umbrella I gave you?"

The sound of water in the kitchen stopped for a second.

Su Xiao stood in front of the sink, holding a bowl in her hand, with dish soap foam dripping down the rim of the bowl.

umbrella.

That sky-blue folding umbrella.

He remembered where the umbrella was now.

That night he gave it to Wu Mengmeng.

Wu Mengmeng supported it and walked away.

"Umbrella..." Su Xiao's voice came from the kitchen a few seconds later.

Su Wan Ning frowned slightly.

"What happened? Did you break it?"

"No, no. It's just..."

Su Xiao stared at the foam in the sink, quickly calculating in her mind.

Su Wanning has a certain characteristic.

Aside from her closest relatives, she hardly interacts with anyone, let alone gives away her belongings.

She used that umbrella for several years, and even though the canopy was washed until it turned white, she couldn't bear to replace it.

If she found out that I gave my umbrella to a young woman with brightly colored hair, it wouldn't be as simple as just turning against her.

That would turn the world upside down!

"What happened?"

Su Wanning's voice had turned cold.

She stood up from the sofa and turned toward the kitchen.

Su Xiao peeked halfway out from the kitchen doorway, her face bearing that classic, conciliatory smile.

"Um, I think I've lost it. I'll buy you a new one another day, no, tomorrow, I'll go buy one tomorrow!"

Su Wanning was stunned for a moment.

Missed.

He meant it's gone!

"You lost it?"

Her voice suddenly turned somber.

"It's not lost, it's gone."

"If it's not there, it's gone!"

Su Wanning exploded.

She stood beside the coffee table, her eyes wide open as she stared at Su Xiao, like a little lion that had been provoked.

This umbrella was a gift from Su Xiao to her on her first birthday in junior high school.

At that time, their relationship hadn't become so strained.

He would still remember her birthday, and he would use his saved allowance to pick out a folding umbrella with a little white rabbit printed on it from the stationery store near the school gate.

She used it for three whole years, wiping it clean and drying it before storing it away each time, and folding it back along the original creases, without even leaving any rust marks on the umbrella ribs.

He actually lost it!

Su Xiao was startled by her appearance.

He genuinely didn't know where the umbrella came from.

In his past life, he gave it away casually and forgot about it, not taking it seriously at all.

But now he realized that this umbrella was no ordinary umbrella for his sister.

"Okay, okay, it's my fault, it's my fault. Don't be angry, I'll definitely get it back for you tomorrow."

Su Wanning did not listen to him continue.

She turned and went into her room, the door slamming shut behind her.

Su Xiao chased after her and stood at the door, raising her hand to knock twice.

"Wan Ning? Wan Ning, I was wrong, okay? I'll find it for you even if I have to dig three feet into the ground tomorrow..."

There was no response from the other side of the door.

He knocked twice more, pressed his ear against the door to listen, but it was completely quiet inside; there wasn't even a sound of footsteps.

He sighed and rested his forehead on the doorframe.

Three dishes and a soup, mopping the floor and wiping the dust, and an excellent performance in the learning report.

The overall performance score had already reached 90 points.

As a result, the umbrella alone caused the loss to go directly into negative territory.

Is this the Cold War sparked by an umbrella?
