After Mistakenly Marking Her Stunning Omega Stepsister - Chapter 1

At the end of September, Yun City had been raining for days, and the sky remained gloomy.

When lunch break ended, the second-year classrooms buzzed with chatter.

Lin Sui was looking down at her phone, scrolling through the school forum. There was a new post from an Alpha venting about being rejected on his first confession.

[Brothers, I’m serious. My family background is solid, and my grades are top-notch. This is the first time I’ve ever confessed my feelings and wrote a heartfelt love letter! And she actually rejected me?! She’s pretty and has great grades, but I’m clearly more outstanding than her. What gives?!]

The comments flooded in one after another.

[There aren’t that many Omegas at our school, right? And which one has particularly good grades?]

[The guy above is out of the loop. A new Omega transferred to our school this year—fair-skinned, beautiful, and quiet. Sounds exactly like the OP’s description. It has to be her!]

A transfer student? There was only one new transfer student this year, so that means…

Lin Sui’s gaze drifted lazily to the desk in front of her, her eyebrows arching slightly.

Wen Xiangzhu. She really is popular.

Narrowing her eyes, she looked back down at her phone.

I’m actually curious—what makes her think she’s so special? Who is this OP anyway? So fragile?

He said his grades are top-notch and he’s an Alpha. There are only a few people that fits, easy to guess. I’ve already figured it out.

What’s there to guess? To be honest, I was there when it happened…

“Sister Sui, I’ve got a juicy gossip for you!”

Lin Sui was engrossed in her reading when a female voice suddenly came from beside her.

“What?” Her fingertip trembled slightly as she turned off her screen and glanced at her desk partner. “Hands.”

Alphas have strong territorial instincts. Even if it’s just a desk, they get annoyed when outsiders touch it.

Zhu Huan raised an eyebrow, clicked her tongue, but still withdrew her hand. Lowering her voice, she said, “Before you came this morning, another Alpha confessed to Wen Xiangzhu with a love letter—the top student in our grade.”

“Oh.” Lin Sui leaned back in her chair, glancing at the back of the girl in front of her while absentmindedly twirling her pen. “And then?”

“What else could happen? He got rejected, of course.” Zhu Huan shrugged, sighing. “Beauty is a curse. That top student who usually looks down on us all has become Wen Xiangzhu’s little lickspittle. His face was so sour—it was hilarious.”

“I wonder what kind of person an Omega like Wen Xiangzhu will finally settle for.”

Lin Sui stopped twirling her pen, casually took a sip from the unfinished milk on her desk, her gaze still fixed on the smooth ends of the girl’s hair in front of her.

Just then, the girl in front turned around, her bright eyes meeting Lin Sui’s as she placed a piece of candy on her desk.

“It’s mint-flavored, to wake you up.”

A corner of the curtain fluttered open in the breeze, and a beam of sunlight raced to Wen Xiangzhu’s nose before vanishing as the fabric fell back into place.

Lin Sui watched her expressionlessly. “I don’t like mint flavor.”

Wen Xiangzhu blinked, her long lashes casting faint shadows beneath her eyes. She pressed her lips together slightly, neither speaking nor removing the candy. She simply turned back around.

Lin Sui glanced at her absently and took another sip of milk.

For over half a month since school started, Wen Xiangzhu had been the same every day: wearing her blue-and-white school uniform, her hair in a mid-length ponytail, always so proper and well-behaved.

She was the epitome of a model student, the type everyone liked.

Zhu Huan, watching from the side, teased, “A piece of candy every day, and never the same flavor twice! So, what flavor do you actually like?”

Lin Sui shot her a glance and stood up. “I’m still hungry from lunch. I’m going to the shop.”

The shop was on the first floor of the school building, located in a repurposed classroom.

The place was surprisingly busy, with students gathered in small groups, chatting.

Lin Sui walked to a row of shelves and casually grabbed a pack of bread. Just as she was about to leave, the conversation of a nearby group froze her feet in place.

“Are you sure? Is it that new Omega transferred to Class 1?”

“Definitely! Chen Huaxing’s best friend told me. You’ve liked Chen Huaxing for so long, and not only did a transfer student swoop in and steal him, but she even rejected him…”

“How ungrateful!”

“Exactly! Isn’t that just rubbing it in your face?”

One of the girls seemed to recognize Lin Sui and quickly tugged at her friend’s sleeve, whispering, “Stop talking. Lin Sui is here.”

Their expressions changed as if they’d seen something deadly. They lowered their heads and hurriedly paid their bills, leaving in a rush.

Lin Sui’s expression darkened. She squeezed the vacuum-sealed package in her hand, glanced at the door, then turned to pay.

As class time approached, the number of students lingering outside gradually dwindled. Lin Sui didn’t immediately return to the classroom. She stood at the third-floor corner, leaning against the wall, listening to the rhythmic footsteps approach, her face impassive.

As the footsteps drew closer, a delicate figure appeared, lightly panting, a hint of panic in her eyes.

“Running so fast?” Wen Xiangzhu asked the moment the girl came into view.

The pretty Omega stiffened, stopping in her tracks and standing obediently before Lin Sui. She bit her lip and lowered her head, looking like a child caught red-handed, her unnatural flush standing out starkly against her pale skin.

“Sis… Sister…”

“Don’t call me ‘Sister’ at school,” Lin Sui said sternly, her face stern.

“Mm…” Wen Xiangzhu lowered her gaze, her long lashes covering her eyes. “I know.”

Sunlight streamed through the corridor window, softening the sharp contours of Lin Sui’s profile. Her slightly drooping, narrow eyes, though weary, were strangely captivating.

Wen Xiangzhu stood before her, looking very obedient, her head lowered, showing no sign of arguing back.

******

After staring at her for a few seconds, Lin Sui’s eyes darkened. “Don’t wander off for no reason.”

The seventeen-year-old Alpha’s overwhelming presence easily affected the Omega. Wen Xiangzhu’s shoulders slumped, her eyes reddening, looking dazed and lost.

Lin Sui’s face was tense, her patience gone. She retracted her pheromones. “Go back. Don’t follow me.”

She glanced at the identical loaf of bread in the other girl’s hand, let out a soft scoff, and turned to walk back to the classroom.

As soon as she sat down at her desk, Zhu Huan stared at her with a strange expression. “Did someone upset you? You just bought food.”

As an Alpha herself and someone who had grown up with Lin Sui, Zhu Huan was keenly attuned to the lingering traces of pheromones on Lin Sui’s body.

“No one,” Lin Sui replied casually.

Just then, Wen Xiangzhu entered the classroom through the back door and took her seat.

It was class meeting time. The bell had just rung when Yang Li, the homeroom teacher, entered the classroom carrying a stack of forms. The click-clack of her high heels finally stopped at the lectern.

Her slightly curled hair was loosely tied back in a low ponytail. Adjusting her gold-rimmed glasses, she set the forms down and leaned against the lectern. “The monthly exam is next week, followed by the National Day holiday. These are dormitory application forms. Students who need them, fill them out and give them to the class president before you leave today. Remember to bring your luggage back to school the day before the exam for dorm assignment. Understood?”

“Understood.”

“Good.” Yang Li nodded and looked around. “Class president, please distribute these.”

Wen Xiangzhu obediently stood up, walked to the lectern, picked up the stack of forms, and began passing them out, counting as she went.

Lin Sui’s interest was piqued. When the form reached her, she took a pen and began to fill it out eagerly.

“Sister Sui, are you going to live on campus?” Zhu Huan asked, fidgeting in her seat and twirling a ballpoint pen around her fingers.

“Um… I’m still considering it.”

She looked up. Wen Xiangzhu had already sat back down, her ponytail brushing against Lin Sui’s desk, leaving a faint strawberry scent in the air.

Zhu Huan shifted, her chair legs now firmly planted on the floor.

“Then you better decide soon. If you live on campus, I’ll join you too. We could even be roommates.”

“Sure.”

Lin Sui acknowledged the question, withdrew her gaze, and lowered her head to examine the form.

Truthfully, it made little difference to her whether she lived on campus or not. Home offered a far more comfortable environment—chauffeured transportation, a maid to prepare meals, and a larger room. But…

If she didn’t live on campus, she would have to see Wen Xiangzhu every day.

Wen Xiangzhu’s room was right next to hers, and they would be in each other’s sight constantly, sharing the same car for the daily commute.

She didn’t think their relationship had progressed to that point.

With this thought, Lin Sui glanced at Wen Xiangzhu. The girl seemed to be focused solely on solving problems, not even glancing at the form.

When the bell rang to end class, Lin Sui finally casually withdrew her gaze.

Now she was certain: Wen Xiangzhu had no intention of living on campus.

It made sense. After finally securing a place in such an upscale villa district, who would willingly give up that comfort to squeeze into a school dorm?

As classmates gradually approached Wen Xiangzhu to submit their forms, Lin Sui watched for a moment, made up her mind, and began filling out her own information.

Zhu Huan leaned over to peek at her work. “You’re definitely staying on campus?”

“Mm-hmm,” Lin Sui replied.

Zhu Huan raised an eyebrow and quickly grabbed a pen. “Then I’ll fill mine out too.”

Hearing this, Lin Sui glanced at her, nodded, and slid the completed application form toward Zhu Huan. “Once you’re done, we can give them to her together.”

“Why don’t you just give it to her yourself?”

Wen Xiangzhu, who was walking ahead, suddenly turned around. Her gaze drifted casually over Lin Sui before settling on the completed accommodation application form. She reached out and gently plucked it from the table with her fingertips. “Just give it to me for now.”

Zhu Huan frowned, her brow twitching. She glanced at Wen Xiangzhu, who had already turned back, then looked at Lin Sui, whose expression was complicated. Sighing, she tried to reassure her, “Don’t… The class president is just being enthusiastic.”

“…Oh.”

Lin Sui didn’t think that suddenly snatching the application form was a sign of enthusiasm…

But fortunately, this little tail who usually followed her even to the restroom seemed genuinely uninterested in filling out the form herself.

When school ended, Wen Xiangzhu collected the completed forms and took them to the faculty office.

Lin Sui packed her belongings, casually slung her bag over her shoulder, and left the classroom with Zhu Huan.

“Want to go shopping? I heard a new bubble tea shop opened in Lu Xing. The drinks are supposed to be really good, and there’s always a long line outside,” Zhu Huan suggested.

“No thanks,” Lin Sui replied, pausing. “My driver’s waiting. Let’s plan something after the exam.”

“Alright.” Zhu Huan nodded. When they reached the school gate, she got into the car sent by her family. “See you at the monthly exam, Sister Sui!”

Lin Sui waved her hand, watching the car drive away. She crossed the street and walked down a block.

The area was deserted, with only an expensive car parked alone.

Lin Sui didn’t want anyone to know about her relationship with Wen Xiangzhu. She had long ago instructed the driver to drop them off a distance from the school gate, so they could walk to and from school separately.

The driver was on his phone when Lin Sui got in. He turned around to greet her, then glanced back in the direction she’d come from before asking, “Eldest Miss, um… where’s the Second Miss?”

“She went to the office. She’ll be a while,” Lin Sui replied coolly.

“Understood.”

Lin Sui put down her bag, her gaze pausing.

Two white handbags, looking quite exquisite, were placed on the seat beside her. She picked up one, peered inside, and asked, “What’s this? Review materials?”

Frowning, she picked up the other and flipped it open. “More review materials… Why buy two copies of the same thing?”

“Madam said you and the Second Miss each need a copy. You both must have one.”

“…”

Lin Sui’s expression stiffened. She pressed her lips together and looked at the handbag in her hand with a complicated expression before throwing it back with visible disdain.

“One portion per person?”

Who wants to use the same thing as that little tagalong?!

******

Inside the office, Wen Xiangzhu obediently pulled up a chair and sat down, her head bowed as she filled out the application form.

Yang Li, seated nearby, sipped water from her thermos and asked with a smile, “Why wait until now to fill it out? Changed your mind at the last minute?”

As the words hung in the air, the girl’s pen paused momentarily. Her gaze lingered for two seconds on the application form beside her, the one bearing Lin Sui’s name.

“Because… I’ve only just decided.”

Yang Li nodded, watched Wen Xiangzhu complete the form, and collected the application.

Just as she was leaving, Wen Xiangzhu hesitated and turned to Yang Li. “Teacher, can an Alpha and an Omega live in the same dorm?”
