In that instant, Lulu Lu completely lost her mind. She pulled a fruit knife from the thigh strap hidden beneath her skirt.

It was something she had prepared in advance after calling Lu Yanyan.

It wasn't that Lulu Lu had long wanted to stab someone.

She was just doing it "just in case," just like her sister.

And then—

"Die!!"

With one thrust, she stabbed at her own sister's neck.

But unlike Lily Liu, whom she had been able to kill so easily before, Lulu Lu didn't succeed this time.

Lulu Lu was only a little over 1.5 meters tall, while Lu Yanyan was over 1.7. One was a minor, the other an adult. They weren't even in the same weight class.

But that gap in size wasn't even the biggest issue.

Lulu Lu had already lost her mind so completely that she ignored the difference between them. Naturally, she had no way of knowing that one of this so-called sister's hobbies was sanda, which Lu Yanyan practiced to stay fit.

Lu Yanyan had been completely unguarded. She never imagined her own little sister would attack her. But after long-term training, her body's reflexes were incredibly fast. She twisted her neck and barely avoided the fatal stab.

Even so, the fruit knife still left a long gash across Lu Yanyan's cheek.

Her stunning face was marred, and Lu Yanyan finally moved.

She boldly grabbed the hand holding the knife. With a clean arm lock, she forced the bloodstained fruit knife to clatter to the floor.

Lulu Lu was subdued very quickly.

Covering the wound on her cheek, Lu Yanyan looked at Lulu Lu, who was roaring at her like a wild beast after losing control of her emotions, and left her with cold words:

"What a disobedient girl. In that case, please stay in the basement for a few days and calm down, my dear little sister."

...

Lulu Lu wasn't locked up for long. After only a week, Lu Yanyan let her out.

And that week had successfully calmed Lulu Lu down. On the surface, she had already "regained her senses."

Even though Lulu Lu had tried to kill her and had almost succeeded, Lu Yanyan still forgave her. Under the excuse of "caring for her mental health," she brought Lulu Lu to her residence near the school.

Then Lu Yanyan began monitoring Lulu Lu's movements. Aside from school hours, Lulu Lu had to stay by Lu Yanyan's side every day. In a sense, it was a kind of half-house arrest.

Lulu Lu acted very obediently. She quickly regained her sister's trust and won back her freedom.

Then, on a bright and sunny noon—

Lulu Lu stepped onto the rooftop of the department store across from her sister's company.

Just like Lily Liu before her, Lulu Lu now had nothing left to hold on to.

She didn't even care whether suicide would make her soul disappear too. To Lulu Lu, if that could end this damned yandere role-playing game, then that would be for the best.

But there was still someone she wanted to punish.

Lulu Lu knew how much Lu Yanyan loved her.

That bond of blood made Lu Yanyan endlessly tolerant of Lulu Lu. Even after the latter had tried to kill her, she was still forgiven.

Lulu Lu understood very clearly that no matter what she did next, she could never truly hurt Lu Yanyan in the real sense.

So then, let her have a taste of watching the person she loved most slip away right before her eyes.

She would turn her own life into the harshest punishment for Lu Yanyan.

Just like how Lulu Lu had watched Lily Liu die before her eyes.

Wearing striking red clothes, Lulu Lu dialed her sister's number.

"Hello, Sis, you're in the office, right~? Look at the rooftop of the department store across from you~"

At that moment, Lulu Lu's voice sounded light and cheerful, just like her name.

"...Lulu! Y-you—what are you doing in such a dangerous place?" Lu Yanyan sounded utterly shocked and frantic. "Get down from there. Don't do anything stupid!"

"Sis~"

Lulu Lu smiled in the direction of Lu Yanyan's office and said sweetly,

"I'm about to become a falling star~"

For the first time in her life, Lu Yanyan's voice was filled with extreme panic.

"Don't, Lulu, don't! Calm down and listen to me. Whatever grievance you have, you can tell your sister. Whatever you want, I'll give it to you! Please, don't do anything stupid. Just stand there and don't move. I'll come pick you up and take you home, okay?"

"Anything I want, you'll give me?"

Lulu Lu kept that same sweet tone.

"Can you bring Lily Liu's life back? If you can't, then doesn't that mean you're 'lying'?"

Deep down, Lulu Lu knew she had no right to say any of this. In the end, Lily Liu's death was inseparable from her own actions. If Lulu Lu hadn't kidnapped Lily Liu, Lily Liu wouldn't have died. She'd probably still be at the school's anime club right now, happily reading manga and chatting.

In a sense, Lu Yanyan was actually innocent. She hadn't really done anything wrong. Everything she had done had only been for Lulu Lu's sake.

But Lu Yanyan's actions had indirectly caused Lily Liu's death, and that gave Lulu Lu an opening.

An opening to vent her hatred.

In a yandere's eyes, she herself is never the one at fault.

The one at fault is always the world.

At this moment, Lulu Lu had fallen into complete madness.

Her logic was simple.

Or rather, as a yandere, her logic had never been the same as a normal person's to begin with.

If she'd already done wrong, then she might as well go all the way.

"Sis, you think the person I love most is just some replaceable object~"

Lulu Lu stepped forward one step at a time until she stood at the very edge of the rooftop, feeling the fierce wind rushing against her face.

"Then to you, am I also just a toy that can be replaced?"

"No! Lulu, please, calm down..."

Lulu Lu tossed her phone down with contempt. Along with it came her final farewell to her sister:

"Goodbye."

With a leap, Lulu Lu ended the short and sinful life of a yandere girl.

The star fell, leaving behind a straight trail.

On the ground, a bright crimson flower bloomed brilliantly, as eye-catching as the clothes Lulu Lu had worn.

...

...

[The girl's love was so intense that it became a sharp blade, plunging into her beloved's chest. When that love shattered, all that remained was a ruined pansy, withering away in the bleak, biting wind of late spring. What a lamentable and delightful poem this is. Don't you think?]

In the pure white space, the strange god's voice was still as lazy as ever. But this time, beneath that laziness, Lulu Lu's soul also sensed a trace of excitement:

[Congratulations, little Lulu Lu. You have successfully reached the normal ending: Falling Star.]
