Lin Wei took a deep breath, suppressing the strange agitation that welled up inside her whenever she saw Su Nuannuan, trying her best to keep her tone calm. “Don’t be nervous. I’m just checking your basics.”
Su Nuannuan obediently nodded, though her body remained somewhat tense.
Lin Wei thought for a moment and decided to start with the most fundamental high school topics, trying to gauge Su Nuannuan’s level.
“Um… what is the Quadratic Formula?”
“What are the Basic Properties of Functions?”
“Do you still remember the simplest Trigonometric Values?”
Su Nuannuan furrowed her brows. What was Lin Wei talking about? Not a single word made sense…
Could it be that she was deliberately making things difficult, testing her on university-level material?
Still, she racked her brains, trying hard to recall, answering hesitantly, occasionally sneaking glances at Lin Wei’s expression.
At first, Lin Wei tried to remain patient and gentle, guiding her along, but as the questions got deeper, Su Nuannuan’s answers became more and more absurd—some even so childish that they made Lin Wei want to laugh and cry at the same time.
Looking at Su Nuannuan’s pitiful expression—clearly trying hard but unable to produce the correct answers—Lin Wei’s gaze grew more complicated…
That nagging doubt inside her resurfaced, becoming clearer by the moment…
Could it be… that Su Nuannuan really is an idiot? Not pretending, not lazy, but genuinely… lacking in intelligence?
This realization sent an inexplicable shock through Lin Wei.
She finally stopped asking questions, sighing helplessly as she looked at Su Nuannuan, whose eyes were slightly red from struggling with the problems.
There was no anger left, only a sense of powerlessness…
“Forget it,” she said, picking up the textbook and pen, “let’s start from here.”
She decided to teach her from the very beginning.
Lin Wei explained seriously, trying to use the simplest language possible for Su Nuannuan to understand.
She didn’t even notice that, in order to help Su Nuannuan see the problems clearly, her body had inched closer and closer, almost pressed against Su Nuannuan’s back.
For a more comfortable posture, her left hand naturally rested on the back of Su Nuannuan’s chair, and from behind, it looked like she was half-cradling her.
Su Nuannuan felt dizzy, concentrating all her attention on the problems, completely unaware of how close Lin Wei was.
As Lin Wei kept explaining, she suddenly caught a familiar scent—the unique fragrance of Su Nuannuan’s body.
She instinctively turned her head toward Su Nuannuan, who was just inches away.
The little girl was frowning, staring seriously at the textbook, her lips unconsciously pouted, completely unaware of how intimate their current posture was.
Lin Wei’s heartbeat quickened slightly, and her throat tightened.
Instead of pulling away, she impulsively leaned in a bit closer under the pretense of pointing out the problems, her chin almost resting on Su Nuannuan’s head, her breath filled with that intoxicating scent.
She felt like she was doing something forbidden, a guilty thrill stirring within her.
Finally, there was a very simple problem, something Lin Wei had just explained.
She asked Su Nuannuan with a hopeful tone.
Su Nuannuan stared at the question for a long time, then suddenly her eyes lit up. Excitedly, she turned her head, “Sister! I got this one!”
Her sudden turn and closeness shortened the distance between their faces.
Lin Wei quickly withdrew her hand from the chair back and stepped back, putting some distance between them. Her eyes darted away nervously, and her voice sounded a bit awkward, “Okay… that’s enough for today. We’ll continue tomorrow.”
Still basking in her joy, Su Nuannuan didn’t notice Lin Wei’s odd behavior. Happily tidying up, she stood up, “Thank you, Sister! Good night!”
Then cheerfully left Lin Wei’s bedroom.
Su Nuannuan secretly rejoiced—so this is what it feels like to get the answers right. Only half an hour and I learned it; looks like I just wasn’t studying seriously before.
Could it be that Su Nuannuan is actually a genius?
Watching Su Nuannuan’s elated figure leave, Lin Wei slowly raised her hand to calm her erratic heartbeat.
What was wrong with her? Why did her heart race so fast whenever she got close to Su Nuannuan, and why did those strange thoughts and impulses arise?
She tried to find an excuse for herself—maybe she’d been lonely too long, and suddenly having a blood-related younger sister awakened unnecessary protectiveness and… a sense of closeness?
Yes, it had to be that.
After Su Nuannuan returned to her room, feeling mentally drained from studying, she quickly took a shower and climbed into bed, soon drifting off to sleep.
In another bedroom, Lin Wei also took a cold shower, washing away some of the heat in her body.
Lying in bed, she habitually opened the Apple Book Bag app and clicked on the latest chapter of Younger Sister Above, Sister Below.
The title of the newest chapter was: Sister’s Obedience Test.
Lin Wei bit her lip. “Obedience Test? What’s that?” She eagerly tapped into the chapter…
The scheming younger sister cornered the fragile and pitiful older sister against the wall, her finger lightly flicking to lift the older sister’s chin, forcing her to look up. Her eyes glimmered with a dangerous and alluring light.
“Sister~” the younger sister’s voice was low and enticing.
“You don’t want Father to find out that you secretly sponsor that poor Student, do you?”
The older sister froze in place, expression tense. How did the younger sister know?
“Guess what, if he finds out, will he still acknowledge you as the disgraceful daughter of the family? Hmm?” Seeing the older sister’s reaction, the younger sister smirked wickedly.
“N-no… please… I beg you…” The older sister’s eyes reddened, tears welling up helplessly, shaking her head, trembling with fear.
The younger sister smiled devilishly, her fingertip slowly tracing the delicate curve of the older sister’s neck. “If you don’t want to be kicked out and left to wander the streets… Sister, shouldn’t you be a bit more obedient?”
“Whatever I say, you’ll do, right?”
The older sister bit her pale lower lip, humiliated and afraid, but finally nodded shakily.
The younger sister pressed closer, their bodies almost perfectly aligned, warm breaths intertwining.
“So good…” The younger sister’s husky voice landed on the older sister’s slightly parted lips, soft as petals, so close it seemed she would kiss her any second.
“Now… close your eyes.”
The older sister abruptly closed her eyes, long lashes still wet with tears, looking helpless and resigned…
Lin Wei stared at the striking words on her phone screen, her breath growing heavy, a surge of heat and excitement rising deep within her.
She twisted uncontrollably in bed, crossing her legs as if that could ease some kind of… excitement?
She buried her face in the pillow, emitting strange whimpering sounds, her toes curling shyly.
What was going on with this novel? It made her heart race…
Only when she grew tired did Lin Wei put down her phone and fall into a deep sleep.
Breakfast the next day.
The dining table was very quiet. The two sisters ate breakfast silently, each lost in their own thoughts.
Su Nuannuan looked a bit troubled—what exactly was Wu Duola’s club activity?
Lin Wei, meanwhile, kept stealing glances at Su Nuannuan across the table, who was sipping her milk delicately.
Looking at her pure, harmless, clueless younger sister, images from last night’s novel, mixed with the scent on Su Nuannuan’s body, flashed uncontrollably through Lin Wei’s mind, making her ears burn.
After breakfast, the two sisters left one after another, getting into the car to head to school.
