Chapter 13
"Given that x squared plus y squared equals 5, what is the maximum and minimum value of 3×+2y?"
"There are several different ways to solve this problem. Which one would you like to learn?"
Matching method, Cauchy inequality method, parametric equation method, substitution discriminant method... He Xi silently recited them in her mind following Bai Shu, and finally shook her head when Bai Shu looked at her. She didn't know how to choose any of the methods.
Bai Shu tutted his words, "Is that so? Then let's start with the most common combination method. Look..."
The pen scraped against the paper, the young man's eyes slightly lowered, his profile revealing a serious expression. A pair of long, deep, sword-like brows glimpsed beneath a few thin wisps of bangs. His eyelids were thin and translucent, and a small brown mole sat just above the crease. His eyelids shifted, revealing a charming demeanor. His nose was sleek, with the tip, bead, and chin forming a perfect line. Down below was a lean neck, and his Adam's apple rolled involuntarily as he spoke, a deadly sensuality. Further down, a delicate, prominent collarbone appeared. And if we continue...
He Xi's eyes became subtle.
"Why are you looking at me? Look at the questions." Bai Shu shifted his chair, his pen-holding hand resting on the draft paper as he leaned closer to He Xi. His low, mellow voice brushed He Xi's ears like a feather, and his scent wafted over her, a faint, sun-kissed scent of lime. He Xi tried to avert his gaze from Bai Shu's collar, but then, hearing Bai Shu's commanding tone, he decided to give up the pretense.
"...So the answer to this question is the negative square root of sixty-five and the square root of sixty-five--" Bai Shu said and subconsciously looked at He Xi.
He Xi suddenly said, "You're naked."
Bai Shu: “…”
"You're really exposed." He Xi seemed to be very ignorant and pointed at his collar and said seriously.
Bai Shu followed He Xi's gaze, and the fingers holding the pen suddenly grasped his collar, the blue veins on his hands bulged slightly. He raised his head again, and an extremely unnatural blush appeared on his brown face.
Bai Shu kept calling him "you, you, you" for a long time but couldn't make any clear explanation. He looked at He Xi with a condemning look, but He Xi looked confused.
The chair legs scraped against the ground with a harsh sound. Bai Shu stood up, turned around, and fled. He Xi then burst out laughing. She was actually a very timid person, but she didn't know that she became so unlike herself in front of Bai Shu.
He looked cold and distant, but when she teased him lightly, his reaction was so funny. I just wonder which girl will be the lucky charm for him in the future.
_
When Bai Shu came back, he had already put on a black base layer over the hoodie with a wide-open neckline. When he sat down, he turned towards her intentionally or unintentionally, as if saying to He Xi, "What are you looking at? Is there anything else to look at now?"
He Xi: "..." He touched his nose guiltily and looked away a little unhappily. Is she some kind of monster?
Bai Shu's face was also cold. He cleared his throat twice, picked up the pen and talked about the following topic as if nothing had happened. As he was talking, he felt a chill in his chest. As if he had sensed something, he suddenly looked up and shouted two words through gritted teeth.
"He, Xi."
"Here." He Xi felt like he was stabbed by a needle.
Bai Shu closed his eyes and said, "Listen carefully."
"Don't you need me, a poor student, to teach you this?" What a sin! Is this retribution for not studying hard since childhood? He had always been advised to study hard, but now he had to put on the teacher's hat and pretend to be serious. To be honest, He Xi was much better at studying than him, even in the subject he was weak in, math, which was on par with him. When Wei Mo told him that He Xi wanted to ask him math questions, he really wondered if she had other motives.
Now he has to teach her a lesson... Does she know how panicked he is? But she still refuses to behave.
"Uh... We've been talking for so long, you must be thirsty. I'll go get you a glass of water." Seeing that the atmosphere was not right, He Xi quickly found an excuse to slip away. As soon as she opened the door, Bai Tang threw herself into her arms. The little girl was wearing a purple printed sweater, a silver-gray gauze skirt, and two cute little pigtails on her head. She looked at her with her round eyes and sweetly called He Xi "sister".
Oh my God, who can stand this!
He Xi can't stand naughty kids, but he has no resistance to cute kids like this.
When He Xi first met Bai Tang, she was like this, clinging to He Xi and asking him to accompany her. In the adult world, few people would be so close to He Xi right away, but children would, and Bai Tang was even more so.
"Little White Sugar."
He Xi squatted down and touched Bai Tang's fluffy hair with a soft look in her eyes, thinking of the second sentence Bai Tang said when they saw her: "I like this sister, can she come home to accompany me more often?" The childish tone was so adorable.
Bai Tang smiled. She liked He Xi's soft and warm hands. She took He Xi's hand and went to find her mother and father in the kitchen.
It's almost time for dinner. Bai Zheng is usually very busy, but today is a rare day off for him, so naturally he has to go into the kitchen to help Chen Xiufang.
"Sugar."
The smile in Bai Zheng's eyes when he saw his daughter was visible even through the thick glasses, always making He Xi daze, thinking of her late father. Once upon a time, there was a man who looked at her like this in her childhood, but now, she walked through the vast sea of people, saw countless men with similar silhouettes and clothes, but she could no longer find him.
-
He Xi took the fruit plate that Chen Xiufang stuffed into her and returned to her room. She originally wanted to go to the kitchen to help.
But as soon as she entered, she was driven away by Chen Xiufang, "Go away, go study hard, this is our adult home ground."
Bai Zheng's face with glasses also smiled: "I finally have some free time. I like staying in this small kitchen with your aunt so that we can come and go and flirt with each other." As he said that, he handed the beaten eggs in his hand to Chen Xiufang who was testing the oil temperature with her hand.
Bai Shu was secretly using his cell phone to check the math questions for his winter vacation homework.
The first part of the multiple-choice questions was fine, but the last one was a real problem. He Xi hadn't known when he would return yet, and Bai Shu stared at the explanation, his brow furrowed slightly. He was just thinking about how to act like he knew the answer to He Xi's question when a delicate, white hand placed a plate of brightly colored fruit on the table. His phone was so hot it almost gave way.
Bai Shu quickly put his phone into his pocket, coughed twice, and tried to act as if nothing had happened, but he was actually extremely panicked.
No, he had to take the initiative and divert He Xi's attention, so he started talking nonsense as soon as he opened his mouth.
"You're just trying to fool me?"
He Xi raised his eyebrows, stuffed a water-soaked grape into his mouth, and retorted, "Isn't fruit better than water?"
Bai Shu was choked.
He Xi said, "Fruit can also quench your thirst... You still want to drink water, right? Okay, wait for me to pour it."
"...No need." Bai Shu turned his head, deliberately not looking at He Xi's expression. He must be very embarrassed in her eyes. "Just now... I was just saying it casually."
"Oh." He Xi didn't seem to care much.
Bai Shu breathed a sigh of relief and quickly put on his current posture as Teacher He Xi and became serious.

Bai Zheng was rarely home, so Chen Xiufang made dumplings today. Bai Zheng loved dumplings, not only because his family was poor as a child and he rarely had the chance to eat them, but also because dumplings were the only time during festivals when the family could gather together.
Chen Xiufang was also very considerate of him. She knew that he enjoyed the process of the two of them rolling the dough together while one made dumplings and talked to each other, so she always went along with him.
Of course, there were not only dumplings stuffed with radish, cabbage and eggs on the table, but also chopped beef, cold spinach with sesame paste, stir-fried bean sprouts, and the hand-shredded chicken that Bai Zheng brought from the vegetable market.
Little Bai Tang is no longer at the age where she needs to be fed. She has already sat down obediently on her own children's chair, looking at the pre-portioned plates in front of her and thinking about which one to eat first.
He Xi laughed and looked at Bai Shu. It seemed that he would never have this worry. He always filled his mouth with chopsticks left and right.
As he chewed, an expression of enjoyment and happiness appeared on his face. In He Xi's eyes, seeing Bai Shu enjoying the food seriously was also a kind of enjoyment for him.
Only white trees can do that.
She confirmed this once again, for the umpteenth time.
Only when he carefully picked up the food, observed it curiously, put it into his mouth tentatively, and the joy that burst out of his mouth and spread from his heart to his eyes, could she be so moved.
Let her believe that food exists to fill the stomach.
It is definitely not a monster that makes your body swell up like a balloon!
And losing weight… doesn't mean losing control of your life, right? He Xi picked up a cabbage and egg dumpling. The crispy and fragrant cabbage paired with the soft and delicate egg, under the influence of the seasoning and spices, wonderfully exploded in his mouth. It was simply too delicious.
I still remember that when Zhang Chaomei came back from get off work, she said that she looked much better than when the winter vacation just started. How could she not look good?
With such a delicious eating broadcast male Bodhisattva, every meal for her is now an incomparable enjoyment.
He Xi didn't know that he had stared at Bai Shu in a trance.
She was completely immersed in her own world of being overwhelmed by the aroma of food.
He was completely unaware that he had been stared at by Chen Xiufang and Bai Zheng, two experienced people. As soon as He Xi left, Chen Xiufang winked at Bai Zheng and whispered in his ear, "Hey, your son looks so useless when he eats. I was worried that he would not be able to find a wife in the future. Now..."
Bai Zheng: "Your son."
Chen Xiufang smiled, "...Unexpectedly, there's a girl who likes this style. This guy is really lucky. But he also looks like he knows nothing. This dull look... is just like you."
Bai Zheng: "Like you."
Chen Xiufang gave Bai Zheng a warning look, and he readily changed his words, "Okay, okay, it's more like me."
He Xi walked downstairs and glanced at Bai Shu, who was following closely behind him. "Okay, let's go up."
Bai Shu became confused. Didn’t she just ask him to take her there?
Why did he suddenly change his tune now? Bai Shu's footsteps hung on the empty staircase, neither going down nor turning around. Suddenly, he saw the girl with her back to him turn around at some point and said to him with a smile, "Just now... I was just saying it casually."
After saying that, before he could react, he had already run away.
Bai Shu slapped him in the face, his shoulders trembling slightly with his heaving chest. The pleasant itch in his throat could no longer be suppressed, and he laughed...this stingy guy.
The girl's profile appeared in front of him again, her fair cheeks flushed, and her complexion was much better than at the beginning of the winter vacation.
He was very relieved.
The New Year is coming soon...and they will meet again at school soon.
