SSS-Class MILFs And Their Yandere Daughters, I Want Them All!-Chapter 377: I’ll Give You The World

The crowd watching was split into two very distinct sides now.

One half stood there with skeptical disbelief written all over their faces.

To them, there was no way this could be true.

Astrid, the famed daughter of Lady Nadia, commander of the Anti-demi-human Alliance being the sister of Mika, a cursed, powerless support-class student?

Impossible. Absolutely impossible. They were convinced there had to be some misunderstanding going on.

"There’s no chance in hell." one whispered, shaking his head.

"She must mean something else, right? Like...symbolically?"

"Yeah, like she’s calling him little brother in a friendly way. There’s no way they’re actually related."

A few of them, of course, were just plain jealous.

Because if what Astrid was saying was true—if Mika really was her brother—that meant he had grown up with her, lived under the same roof as her, and been part of the same family as the Battle Angels themselves.

It was enough to make a few guys grit their teeth in envy.

But the other half of the crowd, mostly the older students weren’t quite as quick to dismiss it.

They’d heard whispers before. About Mika’s strange connections to the Battle Angels.

How those divine daughters of Lady Nadia treated him differently.

How they didn’t just tolerate him—they knew him.

As if there was something deeper there that no one else understood.

So they started murmuring among themselves.

"Wait...What if it’s true?"

"If Astrid’s calling him her little brother, maybe he is related to them somehow?"

"Could he actually be...Lady Nadia’s son?"

The thought was outrageous, but strangely compelling.

It would explain everything—his presence in Solaria Academy, his unnatural closeness to the Battle Angels, even how someone like him could stand toe-to-toe with Astrid without getting instantly obliterated.

And while half the crowd debated and the other half recorded in awe, the truth was playing out right in front of them—

—shouted loudly by the very person at the center of it all.

"YOU ARE NOT MY BIG SISTER, ASTRID!"

Mika yelled as he rolled across the field, dodging another burst of fire.

"AND I’M NEVER CALLING YOU THAT!"

Astrid, hovering above with her arms crossed and her magic still glowing, glared down furiously.

"YOU ARE MY LITTLE BROTHER, MIKA! YOU ALWAYS HAVE BEEN!"

"NO, I’M NOT!" He shouted back, sprinting for cover. "AND I’M NEVER GOING TO BE!"

That was the truth. Plain, simple, and absolute.

Mika and Astrid weren’t related—not by blood, not by adoption, not by any official bond.

But try telling that to Astrid.

If even her own mother appeared right now and told her that Mika wasn’t her brother, Astrid would’ve likely started wrecking the entire academy out of sheer denial.

Because in her mind, Mika had always been and always would be her little brother.

It all went back to the very beginning.

When the five daughters of the Battle Angels were born, they had come into the world within days of each other.

It was almost like destiny, like they had all been conceived at the same moment.

But by pure chance or perhaps fate Astrid had been born first.

Not by a year, not even by months. Just by a few short weeks.

But that was enough for her.

From the moment her mother told her that she was technically the eldest, something shifted inside little Astrid.

At barely three years old, she puffed up her chest and declared herself the big sister of the family.

It filled her with pride and an overwhelming sense of responsibility.

She began to act the part immediately.

She’d walk around with a towel tied around her shoulders like a cape, declare herself the eldest guardian of the house, and boss her sisters around with the seriousness of a general.

"Little sisters shouldn’t run in the halls!"

She’d shout, chasing them.

"You have to eat your vegetables or you’ll never grow up like me!"

She would lecture at the dining table.

"Hmph! I can’t already go potty in the night with pulling Mama along! As expected of an older sister!"

She’d show off her achievements.

She’d even try to braid their hair—often disastrously and when she was done, she’d pat their heads and say.

"There. Now you look cute. Just like little sisters should."

But, of course, her sisters never took her seriously.

They were the same age after all and the moment she tried to discipline them, they’d bite back, or worse—gang up on her.

Astrid would end up crying to her mother almost every night.

"They don’t listen to me, Mama! I’m supposed to be their big sister!"

It was pitiful and adorable in equal measure.

Then, one day, salvation arrived.

Mika.

A tiny infant brought into their family at barely two years old. He was small, quiet, and looked completely lost in a house full of powerful girls. 𝐟𝚛𝕖𝚎𝕨𝗲𝐛𝚗𝐨𝐯𝐞𝕝.𝐜𝗼𝗺

And the moment Astrid saw him, everything clicked.

She ran straight to her mother and shouted,

"Mama! Is he younger than me?!"

Her mother, a little bemused, replied,

"Yes, dear. He’s younger than all of you."

That was all Astrid needed to hear.

From that day on, she officially declared herself Mika’s Big Sister.

And she took that title very seriously.

She’d drag him around everywhere—by the hand, by the shirt, sometimes even by the collar.

She’d help him put on his clothes, poorly, half the time backward.

She’d read him bedtime stories and fall asleep halfway through them, drooling on his head.

She’d discipline him when he got into trouble, puffing her chest out and saying,

"As your big sister, I forbid it!"

And at night, she’d hug him like a teddy bear, refusing to let go even when he squirmed to escape.

To her, Mika was hers. Her adorable little brother.

Unfortunately for her, her sisters didn’t see it that way.

The moment they noticed Astrid hogging Mika all to herself, the entire house descended into chaos.

Every other day turned into a war zone of tiny angels shouting things like,

"Give him back, Astrid!"

"No! I’m his big sister! I’m the responsible one!"

"You’re hogging him again!"

"Because I love him the most!"

Half the furniture in their mansion had been destroyed by those childish fights, and every single one of them had been over the same thing—who got to spend more time with Mika.

Mika himself, being just a helpless toddler back then, had no say in any of it.

He was too small, too powerless, and completely at the mercy of whichever sister managed to grab him first.

He was their baby brother, their favorite toy and Astrid, being the eldest, saw it as her divine duty to protect and claim him.

Nadia and the other Battle Angels, of course, believed it was only a phase.

They thought that as Astrid grew older, she would mature, calm down, and eventually stop treating Mika like her personal doll.

Mika himself had believed that too.

He’d endured years of being coddled, dressed up, and smothered with affection, thinking that one day, surely, Astrid would outgrow it.

But that day never came.

Instead, something far worse did.

Something so painful and so permanent that it twisted Astrid’s gentle big-sister act into something darker, something suffocating.

It was that one tragic incident—the one that had changed Astrid forever.

The one that birthed her hatred toward demi-humans and the same event that made her obsession with Mika spiral completely out of control.

After that day, she refused to let him out of her sight, convinced that if she wasn’t there, something terrible would happen to him again.

To her, Mika was no longer just her ’little brother.’

He was everything.

And in her mind, her role wasn’t a childish game anymore—it was destiny.

That obsession only grew worse with time.

She began to convince herself that Mika didn’t need anyone else.

No lovers, no wives, no friends—just her.

His big sister. The only person who could protect him, understand him, and love him unconditionally.

It was, perhaps, the most dangerous kind of love—one born from fear and guilt disguised as devotion.

Now, that same obsession had reached its peak again.

You could see it in the way she trembled when he defied her.

The way her eyes glistened, begging for validation.

The way she shouted for him to call her ’big sister,’ as if those two words were the only thing keeping her heart together.

And yet, Mika wasn’t the same powerless little boy anymore.

He’d grown stronger, both in power and in will.

He wasn’t going to be Astrid’s pet anymore, not when he understood exactly what would happen if he let her ’big-sister act’ continue.

Astrid would completely monopolize him again, cling to him day and night, manipulate his schedule, and forbid him from even looking at another woman.

She’d undo all his careful progress—all the delicate balance he’d been maintaining between the other Battle Angels, her sisters and his current plans.

If he gave her that power again, his entire strategy to bring the entire family under his influence would crumble.

So no matter how emotional she became, no matter what she promised—he had to refuse.

And now, after what felt like hours of chasing, shouting, and explosions, both of them finally stopped.

Mika was slumped on the ground, panting, while Astrid hovered above him, equally out of breath.

Their clothes were covered in dust, their hair disheveled, and their energy nearly spent—not from combat, but from all the yelling.

Astrid finally wiped the sweat from her brow and descended to his level, her expression softening as she crouched down beside him.

"Mika." She said gently. "Are you finally willing to accept me as your big sister now?"

He groaned quietly, already dreading what was coming.

Astrid smiled, a strangely tender smile that carried both warmth and madness.

"Think about it." She said softly. "It’s the best opportunity you’ll ever have."

"If you just call me your big sister, I’ll cherish you more than anyone else ever could. I’ll guide you, protect you, keep you with me wherever I go."

Her tone became more fervent.

"Anything you want, I’ll give it to you."

"Anything you desire, I’ll make it happen."

"Even if I have to steal from the world itself, even if I have to burn kingdoms to the ground—I’ll do it for you."

She leaned closer, her eyes glowing faintly.

"So just say it, Mika. Accept it. Let me be your big sister..."

"...and I’ll give you the world."

A hush fell over the crowd.

Every single person watching—boys, girls, even the teachers stared in disbelief, envy written across their faces.

The offer she had just made was insane.

Astrid, the untouchable daughter of Lady Nadia, offering her eternal devotion to someone like him?

The crowd erupted in whispers.

"She’ll give him the world?"

"If that were me, I’d call her Big Sister every second of the day."

"I’d die for that kind of affection!"

Even Nuri, hovering nearby, looked stunned for a moment.

Her wide eyes blinked, and then a bright spark appeared in them. She floated forward hesitantly, tugging at a lock of her hair.

"Um...you know, Astrid."

"I actually don’t mind being your little sister. I mean, even though I’m already a princess, I’d totally be fine with it. So, if you want—"

Before she could finish, Astrid turned her head toward her with a glare so cold that even frost formed in the air between them.

Nuri froze mid-sentence, wings stiff, her voice dying to a squeak.

"N-Never mind." She said quickly, backing away with a pitiful whimper.

The crowd couldn’t help but stifle laughs.

Even the mighty dragon princess had just been cowed by Astrid’s glare.

But beneath her pout, Nuri looked genuinely disappointed like she wasn’t asking on a whim, but here was deeper more genuine emotion behind it.

But Mika...Mika just sighed.

He rubbed his temple, exhaling deeply before looking up at Astrid.

"No means no, Astrid." He said finally, his tone calm but firm.

The crowd went dead silent.

"No matter what you say." Mika continued. "no matter what you offer—the world, treasures, anything—I will never accept you as my big sister. That’s final."

He straightened his back, meeting her eyes directly.

"You have to learn to treat me like everyone else. Because no matter what you think, I’m not your little brother."

Half the crowd instantly burst into outrage.

"WHAT?! How could he reject that?!"

"Is he insane?!"

"Trade places with me right now!"

They couldn’t believe it. The cursed boy had just turned down what everyone else would’ve killed for.

But Mika didn’t care.

The only reaction that truly mattered was Astrid’s...

...and it was devastating.

Her face twisted, emotions flickering between heartbreak and fury.

Her hands trembled slightly, her eyes glassy with disbelief.

She looked at him the way a heartbroken child looks at a toy that’s suddenly broken in her hands.

"Mika..." She whispered softly, her voice cracking. "You really won’t...?"

He hesitated for a second—just a second—but then shook his head firmly.

"No."

And that single word shattered her.

Anger, sadness, longing—they all surged together behind her trembling eyes. For a brief moment, it looked like she was about to break down entirely.

But Mika knew this was necessary.

It was cruel, maybe even heartless, but it was better than letting her fall deeper into that illusion she set for herself long ago.
