Jiang Can was having a really hard time suppressing her laughter, so she got up and went for a walk in the yard.
She glanced back every now and then, and saw Huo Zhixing sitting in the living room with a dark expression on his face, occasionally throwing her a not-so-friendly look.
It's as if it's saying: You just wait until tonight!
Jiang Can's face flushed, her heart pounded, and she quickly avoided his gaze.
In the room, Huo Zhixin had finished her bowl of porridge. She looked up at Shen Xiao, like a child waiting for a reward from an adult.
The moment their eyes met, Shen Xiao's heart melted.
So this is what it feels like to like someone.
He had once liked Lin Yuqing, but things were completely different now. When he learned that Lin Yuqing still had feelings for Lu Lishan, he chose to step aside and offer his sincere blessings.
But if Huo Zhixin told him at this moment that she still had someone else in her heart, he would definitely do everything in his power to compete with that man.
Like medieval knights who dueled for love.
He, who used to wield a scalpel, could also pick up a sword and become exceptionally brave.
"Shen Xiao..." Huo Zhixin called him softly, waving her small hand in front of his eyes, "What's wrong? What are you thinking about?"
Shen Xiao suddenly came to his senses and put the bowl aside.
Looking at her clear and pure appearance, his heart seemed to skip a beat.
What should we do next?
A voice inside him cried out: Confess your love!
Suddenly, Shen Xiao sat up straight, cleared his throat, and with a serious expression, pulled his shirt so that it was perfectly straight without a single wrinkle.
Huo Zhixin's eyes widened.
Is this... is she going to have another lesson? Another test?
Heavens above!
"Ahem, Zhixin, I...I have something I want to tell you."
"No, no, no!" Huo Zhixin cried out in despair, tears welling up in her eyes. "I beg you, please spare me! I know I'm taking the college entrance exam soon, and I know I took a year off from school. I absolutely have to get good grades this year! But I've already done the 'Five-Year College Entrance Exam, Three-Year Simulation' course eight times, I've even memorized the punctuation marks! Can you please..."
"Oh?" Shen Xiao perked up immediately. "You're already so familiar with it? Does that mean you can apply what you've learned to all types of questions and come up with solutions?"
Huo Zhixin nodded, looking aggrieved.
"I understand now!" Shen Xiao slammed his hand on the table, his face full of apology. "Zhixin, I'm so sorry. I was so focused on getting you to do the problems that I neglected the fact that you've already done them so many times and ignored your feelings."
"From now on, we will no longer do five-year college entrance exam and three-year mock exams!"
"I can't give you the 'sea of questions' approach..."
Huo Zhixin stared at him, and breathed a slight sigh of relief.
However, the relief didn't last long, as Shen Xiao's words brought him back to his senses—
"I need to continue to improve your skills!"
"puff……"
"I've decided!" Shen Xiao exclaimed enthusiastically, "Starting tomorrow, we'll be working on the secret exam papers! The classic kind!"
“Chen Xiao, that’s enough! Waaah…” Huo Zhixin buried her face in the pillow and threw herself onto the bed.
I really don't want to see him!
"Ah, this..."
Shen Xiao was dumbfounded. What was going on? Wasn't this a confession? Why did he cry while confessing to someone?
Seriously!
I just can't shake this habit of wanting to teach others!
Shen Xiao scratched his head, realizing he had just gone too far.
“My confidante,” he called her softly, “My confidante?”
Huo Zhixin turned her face away, not wanting to pay any attention to him.
“Um…” Shen Xiao stood up and walked to the whiteboard.
There's a whiteboard in Huo Zhixin's room, which Shen Xiao usually uses for her lessons. Now Shen Xiao has another lesson to teach, but…
He picked up a pen and quickly wrote several functions on it.
"Hey, kid," Shen Xiao smiled, "Get up and solve this problem."
"you!"
Huo Zhixin jumped up from the bed, her hair disheveled, her eyes wide with anger.
"I'll give you a reward if you solve this problem!"
"Can we stop doing practice tests from now on?"
"Hmm?" Huo Zhixin blinked, staring at him with a mixture of belief and doubt.
Although he didn't believe it, Shen Xiao wasn't one to break his word easily; he always kept his promises.
It's just one question anyway, so there's no harm in doing it!
Huo Zhixin pouted and glanced at the whiteboard. These formulas weren't difficult to solve, but they required drawing a graph.
Shen Xiao handed her the pen.
Advanced mathematics was no challenge for Huo Zhixin; she quickly solved the problem, complete with diagrams. When she finished the last step, the joy and pride on her face were impossible to hide.
However……
When she took a step back after solving the problem, she discovered that the curve she drew actually formed a heart.
A heart that grows on a number line.
Huo Zhixin stared in disbelief for a long while, frozen in place.
"Shen Xiao, you..."
"This is the question I wanted to explain to you." Shen Xiao smiled gently and took a deep breath.
"Now it's time for questions." He looked at her. "Huo Zhixin, do you understand the meaning of this function?"
Huo Zhixin stared at him blankly, then suddenly her eyes welled up with tears.
"Huo Zhixin, do you... like me?"
The little girl couldn't say a word; her mind went blank for a moment, then she nodded vigorously.
"Very good." Shen Xiao suppressed his wildly beating heart, his palms sweating nervously, but he still looked at her calmly and softly uttered a few words, "I like you too."
"..."
"You like me, which is a sufficient condition, and I like you too, which is a necessary condition. Now that both conditions are met, this is a necessary and sufficient condition."
“Huo Zhixin,” he said, taking her hand and his tender gaze striking her heart, “a problem with necessary and sufficient conditions is… absolutely perfect.”
"Um... how about we continue working on this problem? How about we work on this problem for the rest of our lives?"
