“Onii-chan! The sun’s already shining on your butt! Time to get up, sleepyhead!”
The glaring sunlight streamed through the window and fell on Xia Xi’s face. His eyelids began to twitch, as if he was about to wake up.
Xia Yue stood by the window, both hands gripping the curtains, a sly little fox-like smile on her face. Anyone could tell she was the one who let all that sunlight into the room.
She had just finished her entrance exams and now had a full three months of vacation. She was absolutely thrilled.
“What are you doing~”
Xia Xi used his forearm to shield his eyes—which weren’t even open yet—trying to block out the harsh sunlight.
“We finally get a break. Can’t you let your big brother sleep in a little?”
Normally, entrance exams are held before university final exams, but Xia Xi was already a senior in college. At this stage, the school usually lets students go out for independent internships. In the end, all he needed to do was complete his graduation project and then pass his thesis defense to graduate smoothly.
As for coursework, seniors basically have no in-person classes anymore. If anything, only those who haven’t earned enough credits would sign up for some elective courses to catch up.
Basically, every day was a holiday for Xia Xi. He didn’t even need to go back to campus. So the whole “finally get a break” thing wasn’t really true at all.
“Hmph, sleep, sleep, sleep—that’s all you ever do! If you keep sleeping like this, big brother, you’re going to turn into a pig!”
Not caring how Xia Xi reacted, Xia Yue straddled the blanket right over his stomach.
At that moment, Xia Xi felt like something heavy was pressing down on him.
But since he’d stayed up late playing Golden Spatula last night, he was way too tired to even open his eyes.
Xia Yue wasn’t about to let him keep sleeping. She leaned down, used her tiny, delicate hands to pry open his eyelids, and forced him to wake up.
[Temporary Mission Released: Little Sister’s Resentment]
After barely surviving the stress of her entrance exams, little sister wants to go out and have fun with her big brother. Too bad the host is too lazy, making little sister feel resentful.
Within seven days, the host will gradually transform into a younger version of Xia Yue, with your identity changing to Xia Yue’s younger sister. As your body changes, your memories and habits will change along with it.
Mission automatically completes after seven days.
[Mission Reward:] “Isn’t playing the little sister for seven days reward enough? What more do you want!”
Mission Rejection Penalty: Permanently swap bodies with your little sister, Xia Yue.
The system’s voice transmitted directly into Xia Xi’s mind. That sudden sound jolted his groggy head awake, just a little.
Before he could even process it, a ticklish sensation spread across his face, like something soft and fine was brushing back and forth.
Xia Xi instinctively grabbed at his face and ended up pinching a few strands of hair between his fingers.
“Little sister, get up now! Otherwise, your big sister is going to spank you!”
Xia Yue, who had been saying “big brother” just a second ago, was now calling Xia Xi “little sister.” Her tone had changed from playful and whiny to unquestionably commanding.
Her sweet, girlish voice carried a hint of authority.
Maybe this was that so-called older-sister dominance.
“Noooo~ I wanna sleep a little longer~”
The words slipped out of Xia Xi’s mouth before he even realized it.
Then he froze.
Why would he say something like that? He was a tough guy… wait—his voice!
Why did his voice sound so adorably squeaky?!
Xia Xi shuddered and jolted fully awake.
He grabbed his phone from beside the pillow, opened the front camera, and pointed it at his face.
Staring back was a face that looked about 70–80% like Xia Yue, but much younger and softer-looking, like a squishy little dumpling. On top of that face was even a head of rare, silky white hair!
“How did I turn into this?!”
He remembered what the system mission said—that he would gradually transform into a younger version of Xia Yue. That meant the first change was his head?
Throwing off the blanket and pushing Xia Yue—who was still sitting on him—aside, Xia Xi walked straight to the floor-length mirror.
His body was still the same: tall, strong, healthy. But sitting on top of that male body was a head that anyone could instantly tell belonged to a little girl.
A younger version of Xia Yue? Are you telling me this white-haired, red-eyed cutie is Xia Yue?!
“I know you’re adorable, little sister, but do you really have to stare at yourself in the mirror first thing in the morning? You’re so vain! And on top of that, you pushed your dear big sister aside without a care~ How heartbreaking~”
Xia Yue sat on the bed, leaning to the side with her legs crossed, one hand propped on the mattress and the other placed near her eye, playing the part of a teary-eyed pretty girl.
Seeing Xia Yue act so overdramatically, Xia Xi wanted to roll his eyes and tease her. But for some reason, instead of that, he puffed out his cheeks and let out a little “hmph”—which came off as adorably tsundere.
His habits seemed to be getting rewritten to fit the role of “little sister.”
The scariest part was that memories of being a little sister had appeared in Xia Xi’s mind. If the system had actually replaced his original memories of being a big brother, he might have truly believed he was the little sister.
That cute pout and little “hmph” just now? That was the influence of those new little-sister memories.
“Alright, my heartless little sister, put your clothes on and come out with me to get breakfast.”
Her urge to perform fading, Xia Yue tossed Xia Xi’s clothes to him, signaling him to get dressed quickly so they could head out to buy breakfast together.
Before Luo Xinyu and An Xiaoyu left for Lin Xueni’s house, they’d left bread and milk for the siblings. But Xia Yue insisted—dry bread could never compete with tasty street food~
“What if I told you I’m actually your big brother? Would you believe me?”
Xia Xi tried to reclaim his identity as the older sibling.
“Uh-huh, sure, sure. There’s always that one annoying little sister who wants to be the boss. But you’re not trying to be the big sister—you want to be the big brother?”
Xia Yue nodded obediently, but her words completely contradicted her gesture.
“I mean, yeah, if I had a body as strong as yours, I’d probably want to be the big brother too~”
As she spoke, Xia Yue’s little hand snuck inside Xia Xi’s shirt, patting and poking around like a curious child.
Xia Xi swatted her hand away, let out another “hmph,” and pushed her out of the room.
Gotta admit, this system was seriously powerful. Even though his body—aside from his head—had every male feature, Xia Yue somehow saw him as her little sister and considered those physical traits totally normal for a girl.
Ah~ changing common sense like that—terrifyingly effective.
Strangely enough, after getting this new head, most of Xia Xi’s drowsiness had disappeared. And since his stomach was growling anyway, he figured he might as well go grab breakfast with Xia Yue.
