“Ding-ling, ding-ling, ding-ling...” The sound of the bell echoed through every corner of the campus.
At Linhai No. 1 High School, as the final bell rang on Friday afternoon, students began streaming out of their classrooms. In twos and threes, boys and girls gathered in groups, making their way downstairs.
Some well-developed yet still youthful girls chased after boys who were racing wildly across the plastic track. As the sun set in the west, laughter and cheerful voices filled the air.
Soon, a song currently trending on Douyin began playing from the school’s broadcast room.
“Where you walked, only longing remains, hiding you in my heart, missing you day and night, afraid of your tears, with no one to wipe them away...”
Originally, the song carried a gentle and deeply moving meaning, but the version playing from the school’s speakers was a DJ remix, bursting with energy that made everyone’s hormones surge and unconsciously get into the groove.
“Boom-da-boom-boom-da...”
“Whoa ... whoa...” On the third floor of the high school building, in Class 12 of Grade 10, the song triggered waves of rowdy cheers from the classroom. Some boys sitting in the back even started swaying their heads to the beat, striking playful poses.
“Quiet! Quiet!” “Tap-tap-tap!” Zhang Min, the stern-faced math teacher, shouted from the podium, rapping her pointer against the desk.
Zhang Min was not only the math teacher for Class 12 of Grade 10 but also their homeroom teacher. Young and dedicated, she had graduated from East China Normal University in 2018 and, thanks to her outstanding academic record, joined Linhai No. 1 High School as a respected educator. Two years had passed since then.
As a member of the post-90s generation, Zhang Min had shown remarkable enthusiasm and skill in teaching over these two years, earning the trust and recognition of the school’s administration.
At the start of the autumn semester this year, the school assigned her to lead a class from Grade 10—and not just any class, but a key class.
Though she felt somewhat overwhelmed by the responsibility, it filled her with pride. After all, she had only graduated two years ago, while some of her peers were still struggling to find stable jobs.
Zhang Min was not only highly capable at work but also strikingly beautiful—tall and graceful, with a figure that drew attention, especially the soft curves of her chest.
Class 12 of Grade 10 at Linhai No. 1 High School was a key class, and the teachers assigned to it upheld a strict sense of responsibility and professionalism. As a result, almost every class ran overtime, causing the students to leave ten minutes later than other classes.
“Does anyone still not understand this problem?”
Zhang Min stood tall, her large, beautiful eyes wide open, her nose high and delicate, and her lips rosy. With her long hair cascading down her back, she frowned slightly as she surveyed the restless, cheering students, putting on a stern expression.
As for why I knew so much about Zhang Min—well, I had been in her class for over two months now.
After graduating from middle school, thanks to my excellent performance on the high school entrance exam, I was naturally placed in Linhai No. 1 High School’s key class. Zhang Min had even assigned me the seat right in the middle of the front row—the so-called “top student’s seat.”
During the class committee elections, I was honored to become the academic monitor of Class 12, Grade 10. Zhang Min had initially wanted me to be the class president, but I wasn’t particularly interested. I just wanted to focus on my studies—though, of course, I also had an eye for pretty girls.
Sitting in the middle of the first row, I looked at Zhang Min standing at the teacher’s desk. I knew this was the moment before she was about to explode—the two soft mounds on her chest trembled slightly.
The classmates behind me had also learned how formidable she could be over the past two months, and the classroom fell silent almost instantly.
Zhang Min watched as we all quieted down. I noticed the corners of her rosy, delicate lips curling upward beneath her pretty face, clearly satisfied with our obedience.
“Class, when you get home, make sure to review the sections on arithmetic and geometric sequences thoroughly. This part is crucial. Midterms are coming up soon, so work hard and do your best to perform well.”
After finishing her instructions, Zhang Min saw that we had no further questions and dismissed us for the day.
“Woo-hoo! Yeah!” The class erupted in cheers.
“Zihan, do your best on the midterms!” Zhang Min said with a smile as she gathered her textbooks and pointer from the desk. “Yes, Ms. Zhang,” I nodded in response. Although I had interacted with Zhang Min quite a bit, I still didn’t dare to look directly into her eyes—or rather, I couldn’t bring myself to make eye contact with a beautiful woman. Out of the corner of my eye, I could see Zhang Min’s smile widening even more.
Zhang Min nodded back at me and walked out of the classroom, textbooks and pointer in hand.
I watched her retreating figure. She wore a white blouse tucked into dark blue jeans, which hugged her lower body, accentuating her full and sensual curves. My heart raced uncontrollably. “Ms. Zhang really has a big butt!”
The thought echoed in my mind.
“Ugh, what am I thinking? She’s the homeroom teacher, for crying out loud!” I shook my head to clear the thought.
I had to admit that after returning home, I often scrolled through Douyin on my phone, watching beautiful women from all over the country strike alluring poses. I also had to admit that my heart would race at the sight, but I was always afraid my parents might catch me, so I’d quickly swipe away whenever such videos appeared.
Fortunately, my academic performance was excellent, so my parents never suspected I might be watching such content.
Lost in these thoughts for a moment, I realized most of my classmates had already left. Only a few students on cleaning duty were sweeping the hallway outside the classroom. I hurriedly packed my bag.
“Zihan, I still don’t understand the problem Ms. Zhang explained earlier. Could you help me with it?”
A soft, clear voice came from behind me. I knew exactly who it was and turned around.
“Sure,” I replied with a smile.
Standing behind me was our class monitor, Li Xiaojun, one of the prettiest girls in our class—at least, that’s how I saw it. I thought there were several beautiful girls in our class, though none of them made me as “excited” as the women on Douyin.
Li Xiaojun wore her hair in a cute bun, and her large eyes and high nose bridge were framed by a pair of glasses. Her delicate, oval face and soft pink lips stirred a faint, unfamiliar feeling within me.
As I explained the problem to her, she leaned in close. I had noticed long ago that she carried a scent—something like the fragrance of milk. Especially now, wearing a light, short-sleeved shirt, the milky aroma wafting from her made me feel oddly ... comfortable.
“So that’s how it is ... Hehe, thank you, Zihan,” Li Xiaojun blinked her adorable big eyes at me. “It’s nothing, no need to be so polite,” I replied somewhat shyly, not quite daring to look at her. After speaking, I stood up, picked up my backpack, and headed out.
Walking down from the teaching building, I followed the rubber track to the massive school emblem marked “Lin Hai No. 1 High School.” The emblem was surrounded by a circle of flowers and shrubs. I glanced up at it—even though I’d seen it many times before, it still felt undeniably imposing. No wonder it was the best high school in Lin Hai City.
After a brief look, I stepped off the rubber track and descended the stairs onto the main road leading to the school gate. The weather was gradually turning cooler, and the leaves of the plane trees and maples lining the road had begun to wither and yellow. The fading twilight seeped through the branches and leaves overhead, casting a gentle glow on the road. A cool autumn breeze swept by, sending colorful leaves fluttering down one after another.
“Winter must be coming soon,” I thought.
“Zihan, wait for me!” Li Xiaojun called out as she came down the stairs. “Ah, sure,” I replied, turning back to look at her and stopping to watch her approach.
“Zihan, I heard our school is getting exchange students this semester, and they’ll probably be in our class,” she said as we walked side by side toward the school gate. Since girls tend to develop earlier, I was 173 cm tall, and Li Xiaojun seemed only slightly shorter than me.
“Is that so? That’s great, a warm welcome to them,” I said, my eyes fixed on the school gate as I wondered how best to say goodbye to Li Xiaojun.
“Yeah, I hope a really handsome guy comes. Hehehe,” Li Xiaojun giggled. She was already pretty, but when she smiled, she looked even more charming.
In that moment, seeing her standing there gracefully in her school uniform made my heart flutter a little. Of course, I didn’t know what that feeling meant.
“Uh ... yeah,” I replied awkwardly. Why wish for a handsome guy? Wasn’t I right here?
Making small talk with her, I finally endured the awkwardness until we reached the school gate. Fortunately, her home was in a different direction from mine. After saying goodbye, I boarded Bus No. 2 and headed home.
My family lived in the Binhai New District, the most developed area of Lin Hai City. Though located by the sea, it was considered the city center.
Bus No. 2 from the school gate went directly to my residential community, making it very convenient for me to go home every weekend.
Arriving at the community entrance, an unfamiliar security guard watched me approach with an indifferent expression, as if I owed him millions. I ignored him, took out my access card from my backpack, and swiped it. Instantly, the guard’s face transformed like a hat trick, breaking into a warm smile.
Once inside the community, I walked toward the innermost area. My house was a standalone villa, though there were many similar villas around. Still, it felt more comfortable than the high-rise buildings near the entrance. At least our villa had a backyard we could use. My dad and I had been thinking about digging a small swimming pool someday so we could enjoy a refreshing swim at home during Lin Hai’s scorching summers.
