"Set A is contained in set B, first of all, we need to discuss whether it is an empty set ....."

The math teacher was talking about a topic that Si Fang had already learned by heart in front of the blackboard, and she simply emptied her head, and planned with joy how she would play with her uncle on the beach tomorrow.

She had never gone out with her uncle, and she had been looking forward to it since she got up this morning, for seven hours and forty-two minutes, every minute and every second.

There was a sudden knock on the front door of the classroom, the math teacher hurriedly stepped down from the podium and opened the door, and the head teacher, Li Yizhen, leaned in and said something to her.

I saw the math teacher nodded, and his eyes suddenly fell on Si Fang's body, "Si Fang, pack up your things, someone will take you home." ”

Envious eyes were cast at her, and she hurriedly answered and hurried out of the classroom.

In the hallway, a person stood with a backlight, more than anything else in the world, and it also quickened her heartbeat.

"Uncle." Si Fang called him happily, quickened his pace and ran towards him, chattering, "Didn't you say that you would go to the beach tomorrow, why did you come to pick me up in the afternoon?" ”

Her amusement didn't seem to infect him, and he still stood with a solemn face, just like that, motionless.

The smile on Si Fang's face gradually disappeared, and he suddenly began to panic a little in his heart, "What's wrong?" ”

"Your grandfather, he...."Gu Wei pursed his lips and looked at her eyes, as if he couldn't bear it.

"Critically ill."

His short sentence was like five thunderbolts, and Si Yu seemed to lose support all of a sudden, and his body shook invisibly.

Gu Wei's hands hanging by his side slowly lifted, but they retracted like an electric shock when they touched the corners of her school uniform.

He just looked at her worriedly, and said tentatively, "Si Fang...."

This sentence aroused her thoughts, and she grabbed his cuffs tightly with both hands and asked anxiously, "Where is it.... Where is Grandpa now? ”

"At the county hospital, I've booked a ticket back." He took advantage of the situation to hold her arm to prevent her from falling, "It's the plane in three hours." ”

He couldn't hear what he was saying clearly, but just broke free of his hand and ran out like crazy.

The bag on her back fell to the ground, and it didn't stop her from running.

Since Si Fang was a child, her parents have been busy with work, so that her childhood was almost only her grandparents and Gu Wei, and her relationship with them was naturally closer.

Grandpa's body has always been very strong, how could it be ..... this time

How could it be.....

Si Wei stumbled towards the door of the school building, but accidentally bumped into someone.

She looked up and saw Jiang Yihuai's slightly stunned face from the hazy tears.

He also just came back from skipping class from the commissary, and he didn't expect to bump into her crying mess.

Visibly flustered, he hurriedly reached out and rubbed her back, trying to say something but unable to speak.

Si Fang didn't have the heart to linger with him, and hurried out of the gate and ran towards the school gate.

Gu Wei chased all the way from the teaching building, but only saw her last figure disappear at the door, and inside the door was Jiang Yihuai, who was stunned in place.

The eyes of the two intersected, only for a moment, but there seemed to be an undercurrent surging.

Gu Wei ignored Jiang Yihuai, who was full of questions, and continued to chase Si Wei out.

Si Fang was running around on the road like a deer that had lost its direction, and suddenly, a force grabbed her who was out of control, forcing her to stop.

She turned around, it was Gu Wei.

"What are you doing!" She shouted out this sentence almost with all her might.

"Si Fang, calm down." Gu Wei tried his best to speak softly, and patiently said to her, "What is the use of you going to the plane in three hours?" ”

"But... But... Grandpa, he—" She suddenly lost her edge, squatted heavily on the ground, and choked up.

She buried her head in her lap and sobbed quietly, helplessness and despair instantly enveloping her heart.

Gu Wei sighed, slowly knelt on one knee, and opened his arms to embrace her softly.

His embrace was warm, his heartbeat was strong, and there was no word of comfort, but it made her feel at ease for no reason.

Later, Si Wei was confused, but he had the impression that Gu Wei took her all the way through the noise of the crowd.

Everything around her seemed to have nothing to do with her, and all she could see was his tall back.

........

The hospital was a cold color of pure white, which made Si Wei breathless, but she still cheered up and let Gu Wei pull her into the elevator.

Around eight o'clock in the evening, it is the time when the hospital is crowded, and the elevator is naturally overcrowded.

A few more people squeezed into the elevator, just in time to squeeze away from the hand she was holding with him.

Si Wei no longer had the courage to pull it back on, and Gu Wei had no intention of looking back for her.

There are only a few people between them, but it seems to be separated by mountains and seas, she can't cross it, he can't walk.

From the first floor to the fourteenth floor, all Si Fang could see was his back and the rapidly rising figures.

The elevator door opened, Gu Wei strode out of the elevator and turned back to wait for her, while Si Wei struggled to push through the crowd and walk towards him.

Almost every time, it was like this, it was she who walked towards him.

Si Fang glanced at him with complicated eyes, but he turned his face away, and his eyes fell on Si Fang's parents, who were already waiting by the elevator.

He knew they would be waiting here, so he had to be careful with every move.

Gu Wei lowered his eyes and called in a low voice: "Brother, sister-in-law." ”

With just this sound, Si Fang understood why he was like this, but she could never understand him.

"Mom, how's Grandpa?" She put away the unknown emotion in her heart and turned her head to ask.

Si Fang's mother stopped talking, looked up at Si Fang's father, and choked up after getting acquiescence: "Yes... Advanced lung cancer. ”

Even though Si Fang had made sufficient psychological preparations, he still burst into tears in an instant.

She seemed to have grown up all at once, not hoarse, not emotionally out of control, but just silent.

"What room is it?" Her voice was surprisingly hoarse.

“1407。”

She wiped the tears from the corners of her eyes with the back of her hand, took a heavy first step, and then step after step, and everyone followed her in unison.

Standing in front of the door, looking through the glass window, Si Fang's grandfather was lying on the white bed in the hospital, with a few cold tubes stuck in his body, so fragile that they seemed to shatter at the slightest touch.

And Si Fang's grandmother was sitting on the wooden chair next to the bed, her eyebrows fluttering and saying something.

Grandma Si suffered from Alzheimer's disease a few years ago, and she spoke and acted like a child.

A hand crossed the door and pushed open the door, she turned her head to look at it, just opposite Gu Wei's eyes, but it was only for a moment.

He walked straight into the ward, and Si Fang followed closely with a blistering mind.

"Lao Xu's cat gave birth to a kitten again, I want to raise one, but you won't let me raise it." Grandma pouted like a child who couldn't eat candy.

""Huanzhu Gege" is on the air again, this time you have to watch it with me episode by episode."

"I want to eat the spring cakes you made, when will you get up and make them for me?"

"Jianjun...."Grandma's chaotic eyes suddenly filled with tears, "Do you think this is good?" ”

"I don't want the kitten, I don't watch the TV series anymore, I'll make the spring cakes for you to eat...."

"Arise and speak to me.... I've been good lately..."

Si Yan held back his tears and bit his lip to prevent himself from crying.

Grandma married her grandfather at the age of eighteen, which was the words of the matchmaker and the order of her parents.

And this marriage is a lifetime.
