My Sister's Mental State is a Bit Unusual

"I curse every scumbag to suffer endless torment! May they die a horrible death!"

In the classroom, Luo Wei suddenly awoke from this angry curse.

Like a drowning man, his chest heaved violently as he gasped for air, his forehead covered in sweat.

The surrounding classmates were startled by Luo Wei's sudden outburst.

"Luo Wei? Are you okay?" his female deskmate looked at him with concern. "Are you feeling unwell?"

Luo Wei stared at his familiar deskmate and the familiar classroom, momentarily dazed.

I'm not dead? I'm still alive??

He quickly looked down at his chest. His white shirt was clean and tidy, without a trace of blood.

But just a second ago, he remembered Helena's tentacle piercing through his heart.

Luo Wei raised his head, looking around in surprise.

The girl who had been dumped was still wiping away tears, while the surrounding classmates who had been condemning the scumbag now all turned to look at him curiously.

Not only was he not dead, but he had even returned to the classroom where it all began.

Time reversal?

As he pondered this, a familiar game interface floated before his eyes.

[Version 2.0 Update Complete]

[Please investigate the case of missing students at Saint Callen Royal Academy of Magical Science]

[Affection System Unlocked]

[Potion/Alchemy System Unlocked]

[Save Point Updated]

[Available Reloads: 4/5]

[Friendly Reminder: The game cannot be restarted. For your own safety, please use each reload carefully.]

Luo Wei looked at the game prompts before him speechlessly. This meant he would have to face Helena again soon.

And if he died five times...

He would really be dead for good...

What the hell! Why did this system update so slowly? Why couldn't it have appeared earlier?

Complaints aside, Luo Wei knew this was his only hope of survival now.

He quickly scanned through the information.

The 2.0 version of the game was largely similar to what he had played before, but the chapter was entirely new.

As for this so-called campus disappearance case, he wasn't sure if it was related to Helena, given her past...

His thoughts returned to the moment before his death.

That twisted, maniacal smile, the sanity-draining mental pollution, the invisible murderous tentacles...

No matter what, he never imagined Helena would become like that.

Transformed into a twisted being that terrified him.

Even now, he vividly remembered the intense pain of his heart being pierced.

An excruciating, heart-wrenching agony.

Even with the ability to reload, he didn't want to experience that again.

Luo Wei clenched his fists tightly.

There won't be a next time.

He didn't have much time to think as a male classmate called out—

"Luo Wei, your girlfriend is here to see you!"

The inevitable had arrived.

The chattering classmates fell silent, all looking towards the classroom door.

Even though he was somewhat prepared, Luo Wei's heart still pounded uncontrollably.

He struggled to control his emotions as he slowly turned to look at the girl bathed in sunlight.

"Ex-excuse me..."

"Is my brother here?"

She stood there timidly, just like she had the first time.

A beautiful, pure girl like an elf, captivating the boys and causing the girls to whisper among themselves.

But none of them could have imagined that beneath that angelic exterior was a heart as twisted as a monster's.

"Brother! I've finally found you!"

The girl's sapphire eyes were filled with nothing but Luo Wei's image.

She ran over to him.

But this time, Luo Wei didn't go to meet her.

He unclenched his tightly gripped fists and took a deep breath.

Survival was paramount; now was not the time to confront her.

Luo Wei looked at the girl and put on a gentle smile like that of a kind older brother.

"Helena."

Helena came up to Luo Wei, feeling nervous under the various gazes of those around her.

She shyly lowered her head.

"Brother, let's go home quickly..."

"Helena has been waiting for you for so long..."

Luo Wei silently observed her. If he hadn't died once already, who could have spotted any flaw in this seemingly harmless and adorable girl?

But if he angered her, if she thought he had betrayed her or cared about others...

She would suddenly snap and kill him...

So he absolutely, absolutely could not say the wrong thing!

The atmosphere was silent for a moment.

Helena cautiously raised her head to look at Luo Wei.

"Brother?"

"Hmm?"

She fidgeted with her hair nervously, "Did Helena do something wrong..."

"Not at all," Luo Wei looked at her with a gentle smile.

"It's just that Helena has changed so much, I almost didn't recognize you."

"Is that so..." Helena lowered her head again, like a child who had done something wrong.

Perhaps sensing something odd in the atmosphere between the two, the female deskmate asked curiously:

"Luo Wei, is this girl your sister?"

Luo Wei nodded, "She's my sister. We haven't seen each other for a few years."

Hearing that she wasn't his "girlfriend" but just his sister, the female deskmate felt relieved, thinking she still had a chance.

She winked at Luo Wei, "As her brother, don't be so distant with your own sister! Look how scared she is!"

"Come here to big sister~" she said, reaching out to take Helena's hand warmly.

But Luo Wei beat her to it, grabbing Helena's hand first.

"Eh?" The female deskmate was taken aback.

Luo Wei put his arm around Helena, shielding her from everyone's view.

"My sister is shy and doesn't like interacting with people," he said with a smile.

It was best not to let the current Helena chat too much with his classmates. Who knew if she might hear something she didn't like and get agitated enough to kill someone?

"If there's nothing else, we'll be heading home now. Bye."

The female deskmate stared at his handsome face, nodding dazedly.

"Oh... okay, bye..."

Luo Wei held Helena's hand and left the classroom without looking back.

On the way home, Helena lowered her head guiltily.

"If brother doesn't like me coming to your school..."

"Helena won't do it again next time..."

Hearing this, Luo Wei shook his head.

"How could that be? I was just worried you might not get along with strangers."

Helena looked up in surprise.

"Is that so! So brother wasn't annoyed with me?"

"Of course not," Luo Wei gently stroked her light-colored hair.

"How could I ever be annoyed with you?"

Hearing Luo Wei say this, Helena beamed like a happy child, her eyes curving into beautiful crescents.

"So brother was really thinking of me!"

"Brother is so good to me!"

"Then..."

Helena looked at Luo Wei, finally asking those two questions.

"Can brother stop going to school?"

"Helena wants brother to stay home with me!"

Although Luo Wei's expression didn't change, still wearing that calm smile, he was actually panicking inside...

These two questions could be said to be the fuse that led to his death last time.

So he absolutely could not answer wrong!

Looking into Helena's blue eyes full of expectation, Luo Wei didn't hesitate at all.

"I promise you, sister."

"Really?!" Helena's eyes widened.

"Of course it's true," Luo Wei said with a straight face.

Life is like acting, it all depends on your performance.

Not to mention his [Charm] attribute was already maxed out.

This time... coupled with this face, the effect was even more potent.

He looked at Helena, flashing a dazzlingly gentle smile, and said in the most sincere tone:

"My little Helena is the one I love most. How could I not want to spend every day with you?"

Helena was stunned.

She gazed at that close, seemingly magical smile, her eyes filled with adoration.

"Brother..."

"Loves Helena..."

"Helena loves brother too..."

However, her reaction exceeded Luo Wei's expectations as she began to tremble uncontrollably.

Helena alternated between muttering to herself and flashing strange smiles.

Brother...

Such a gentle brother, such a smile...

Is mine... can only be mine...

"Helena!?"

Luo Wei suddenly felt a tremendous force gripping his hand tightly, dragging him towards home.

"Brother belongs only to me..."

"No one will take him away..."

Helena looked around suspiciously, eyeing all passersby warily, as if afraid they might snatch her brother away.

Her expression gradually became more and more unpredictable.

At this point, Luo Wei's forced calm expression began to crumble.

He was starting to feel a bit scared...

Wait, how did things turn out this way even when he answered correctly??

Luo Wei suddenly realized he might have gone too far.

He hadn't considered that Helena's current mental state was a bit unstable and couldn't handle even a little stimulation...

With a loud slam of the door,

Luo Wei found himself back in his own home.

Turning around, Helena revealed an uncontrollable smile and excitedly said:

"Helena will prepare dinner for big brother! Helena needs to go out for a bit!"

"It's been four years! Helena has been practicing her cooking skills all this time!"

"Big brother must wait obediently at home for me!"

Hearing that Helena was leaving for a while, Luo Wei felt inexplicably relieved.

But what he didn't expect was a dark shadow flashing by, and Helena instantly appearing behind him.

Luo Wei's arms suddenly felt a sharp pain.

"Helena! What are you-?"

A crisp sound rang out in the quiet house.

Luo Wei felt a cold sensation on his wrists as a pair of heavy metal handcuffs firmly locked his hands together.

He looked at her in shock.

Helena gazed at her brother, her smile deepening.

"Big brother must wait obediently at home and not try anything sneaky~"

"If Helena finds out, she'll be very angry~"

A few words from the author:

This book features various types of yanderes: aggressive, isolating and manipulative, captive and controlling, dependent... (yandere enthusiasts will be fully satisfied)

Mystery and puzzle-solving fans shouldn't miss out either~ There are many Lovecraftian elements, and the male lead is a classic Lovecraftian legendary investigator.

Warning! Some yanderes are extremely aggressive, and the male lead walks the line between life and death. If you can't accept this, please read with caution. (I'm saying all this in hopes of connecting with readers and avoiding unnecessary arguments.)
