Su Xun has always been somewhat unbalanced in her studies, and mathematics has always been her weakest subject.

Actually, everyone in the family is good at math. Although Su's father and mother are not highly educated, they were both very good at math when they were in school. Their younger brother, Su Mu, who was in the second grade of elementary school, also showed a talent for math at the age of seven.

Su Xun's mother often looked at his math test papers and exclaimed, "Your math score is so high, most people wouldn't be able to get this score." Su Xun thought it was because he wasn't smart enough.

This made Su Xun doubt once again whether he was really a child of the Su family. The last time he doubted it was about his height.

Pei Ke is very smart. His grades are always among the top in the grade, especially in math, where he almost always gets full marks.

Su Xun was very envious, but she couldn't bring herself to ask him how he got such a high score. They hadn't interacted much before, so it was impossible for her to ask him.

Actually, since the start of the semester a month ago, the two of them haven't had much interaction. During breaks, Su Xun would quietly sit and review what she had just learned, and sometimes she would go out to chat or go to the bathroom with Tang Shi.

Pei Ke was mostly quiet, spending his time solving Rubik's Cubes and reading comics.

Su Xun didn't understand what Pei Ke liked, and Pei Ke found Su Xun's dullness uninteresting.

Before school ended that afternoon, the homeroom teacher, Ms. Li, stepped into the classroom. As usual, she first scanned the whole class before saying, "We've been in school for a month now. We have two consecutive math classes tomorrow morning, so how about we do a short test to check how well you've been learning over the past month?"

After he finished speaking, the students below sighed and groaned, especially a few of the bolder students who clearly expressed their complaints.

Tang Shi was one of them, gripping the edge of the table with both arms and sighing with his head tilted back.

Su Xun lowered her head slightly. Although she had been studying diligently every day, she really wasn't confident about this exam. In fact, she always studied hard for every math exam in the past, but the results were always disappointing.

Pei Ke didn't care. He usually did math olympiad problems and didn't care about regular exams. He packed his things, put the homework he was going to finish into his schoolbag, and turned around to see his deskmate with her head down, seemingly lost in thought. He was about to say something to encourage her, but then he remembered that she usually ignored him when he called her, so he swallowed back what he was about to say.

After school, Pei Ke was about to go back to her room to do her homework as usual. Just as she put on her slippers, she heard her mother, Ms. Lin's voice: "Xiao Ke, you're back! Your uncle's daughter, Lingling, came to our house to play. She's doing her homework in your room now. Go and teach her."

"Why is she here again? And Mom, how can you let someone into my room?" Lingling is his cousin, four years younger than him. She's always been a troublesome child, though she's toned it down a bit since starting school, but her fearless nature remains. Lingling's parents are usually quite busy and often stay at Pei Ke's house.

Hearing her son's words, Lin's mother pretended to be serious and said, "What do you mean 'again'? Lingling is your sister, you have to spend time with her. I don't care, you have to help her with her homework today, otherwise you can't eat the cake I just made."

Pei Ke liked cakes, and his family often made them for him. Hearing his mother's unreasonable request, he could only pout and go upstairs to his room: "Fine, I'll teach him."

Standing in front of the door, Pei Ke took a deep breath and then pushed the door open.

Sure enough, it was pretty much as I expected. The books that should have been on the bookshelf were now scattered in a very messy state on the floor, in the corners, and on the bed.

Beside the desk, a little girl, who looked to be six or seven years old and was wearing only one slipper, was biting a pencil stub and frowning as she looked at her workbook.

Pei Ke rubbed his forehead like an adult and said helplessly, "Xiang Siling, didn't I tell you not to bite your pen? It's dirty."

Hearing the voice behind her, Lingling immediately stood up and hugged Pei Ke tightly. "Cousin, you're finally back! Come quickly, these questions are too difficult. Please teach me, or I'll get scolded by the teacher again tomorrow."

As Pei Ke peeled the little figure off his body, he said, "Sit down properly first, let me take a look."

Pei Ke took out a pen from his pencil case. "Fill in the blanks according to the text: 'Giving roses to others,' what's the next line? Xiang Siling, you're saying this kind of question, which can be answered simply by flipping through the book, is difficult?"

"I didn't read the question, hehehe, I'll flip through the book now." Lingling scratched her head sheepishly, took out her textbook, and read aloud, "Giving roses to others leaves fragrance on your own hands, that's it! What does it mean?"

"It means that even a very ordinary and small thing, such as giving someone a rose, can bring warmth that will slowly rise and spread in the hearts of both the giver and the lover of the flower."

Lingling nodded, then looked at the pen in Pei Ke's hand. It was a simple pen with a small moon inlaid on the cap, very exquisite. "I understand, so," the girl's eyes darted around, "cousin, please give me this pen. It will leave a lingering fragrance on your hands."

Pei Ke did not refuse, knowing that refusal would only bring more trouble, so he nodded in agreement.

The first and second periods on the second day were math tests, and Ms. Li arrived in the classroom early to distribute the test papers. The entire classroom was quiet, with only the sound of the teacher distributing the papers.

Yesterday after school, Su Xun went to her grandmother's house with her family to celebrate her grandmother's birthday. She didn't study at all and was very worried about today's exam. She lowered her head and prayed silently in her heart.

Pei Ke unzipped her pencil case, took out her usual pen, and realized she had given it to her cousin yesterday. She then took out another pen to write her name, only to find it was out of ink. She had to take out other pens, but unfortunately, she had forgotten to replace the refills in all of them.

Su Xun saw this scene and, although she felt quite embarrassed, she still gently touched Pei Ke's arm with her fingertips and handed him the pen she was holding.

Here, take it.

Pei Ke felt a poke on his arm, followed by a soft sound from his side.

She offered to lend him a pen; I really didn't expect that.

Pei Ke took the pen; it was a white ballpoint pen with a cute rabbit design. "Thank you, and also," she paused, then added, "Relax during the exam; it won't be too difficult."

After saying that, Pei Ke gave her a big smile, as bright and radiant as the sunshine outside.

Perhaps even someone as brilliant as Pei Ke encounters trouble and needs help just like her. And ordinary people like her can also offer help to others.

Perhaps everyone can feel free to make mistakes and be careless, because there are always people in life you can rely on and trust. They could be your parents, your friends, or even someone you don't know well.

Su Xun, perhaps you don't need to be so careful in your life, and you can try to make mistakes.

She thought to herself.
