All the Heroines Who Showed Their Overwhelming Emotions on Me Have Mentally Broken Down and Gone Insane, so Now My Only Choice Is to Pamper Them Endlessly to Avoid Total Chaos — Sweets Work Best on Lovesick Heroines - Chapter 14-15

Chapter 14: “Stepsister’s Obsession”

Kaname Aotori and Kokoa first met when he was six years old and she was four.

Because their parents were friends, it had become a tradition for the families to get together during long vacations. However, Kokoa always hid in the shadows, and even when he invited her to play at the park or handed her a controller to play a game, she shook her head vigorously from side to side.

She was extremely shy around strangers, and each time they met, he tried to ease her wariness. But Kokoa always kept two or three steps’ distance from him, and if he tried to approach too forcefully, she would blush with embarrassment and hide—that cycle repeated endlessly.

That dynamic continued for several years until one day, their parents decided to remarry.

He was eleven, and Kokoa was nine at the time.

They began living under one roof, and thus became stepsiblings.

Five years passed from there. As they went through puberty together, Kokoa’s attitude toward him gradually began to change shape.

In the beginning of their new life together, Kokoa still avoided him even inside the house, but around the time he entered middle school, she started spending more time in the living room. At first, she sat cross-legged at the edge of the sofa, but before long, sitting next to him became the norm.

Quite naturally, she began visiting his room with an “Onii-chan,” and when she had something she did not understand in her studies, she would pluckily ask him, “Teach me this…”

Yes. The Kokoa in his memories had always been quiet and demure, the kind of little sister who would murmur a soft “Onii-chan…”

—Or so it should have been.

“I looooove yoooou♡♡♡ Kaname big bro, I looooove yoooou so muuuch♡♡♡”

Kokoa’s scream rained down from the second floor once more. Probably because it came through the door, it was muffled as before, but there was no mistaking her voice for his little sister’s.

And yet… he could not help doubting his ears.

This was Kokoa…?

If so, what was she doing in her room…?

“…………”

He had to check. As her big brother, he needed to assess his little sister’s condition.

He quietly slipped off his shoes. Leaving his bag in the entryway, he ascended the stairs while muffling his footsteps. Step by step, he took the utmost care to avoid making the floorboards creak.

All the while, Kokoa kept shouting.

“And what the hell is that woman…! Kissing my Kaname big bro! When I haven’t even yet!”

That woman must have been Iori. Along with her angry shout, he heard a sound like her punching the bed.

He reached the second floor. That was when he realized it. The voice was not coming from his little sister’s room, but from his own room.

…Why?

He cautiously placed his hand on the doorknob. He opened the door just a few millimeters and peered inside through the narrow gap.

“—!”

He could hardly believe his eyes.

Dressed in a shirt and shorts as loungewear, Kokoa lay sprawled on his bed. That alone might have been fine. But Kokoa was engaged in something utterly outrageous.

“Haa♡ I want Kaname big bro to sleep next to me like this every day…♡ I want to fall asleep while he squeezes me tiiiight♡”

She had wrapped her arms and legs around his beloved body pillow like a snake. On top of that, she buried her face into the regular pillow where he rested his head, as deeply as she could.

This really was his room, right…?

He pulled his face away from the door gap once. When he glanced back, the nameplate reading “Kokoa” dangled from the door directly across from him.

No mistake. That meant Kokoa had snuck into his room while he was away and was now indulging in solitary oddities using his bedding.

He returned his gaze to the door gap.

“Suuu… Haaa… Suuu… Haaa…♡”

With her face still buried in his pillow, Kokoa took deep breaths. As if inhaling the finest aroma.

“Mmm…♡ Big bro’s scent…♡ It calms me down so much…♡”

Her mutterings grew increasingly heated.

Next, Kokoa began stroking the body pillow she had entwined her limbs around, with an enraptured gaze. As if doting on a beloved pet.

“If only this body pillow were the real big bro… Haa… Haa…♡”

Her body rose and fell, and her breathing gradually grew ragged.

“Big bro… Ha… Kaname big bro…♡”

And then, the arm that had been draped over the body pillow slowly moved toward her lower body.

It stretched into the shorts at the base of her slender bare legs—and—.

“Wait, wait…!”

“◎△￥○＄♪×＆％—!?”

Unable to simply look away, he flung the door open. Kokoa’s wordless shriek swallowed up every sound in the room.

Chapter 15: “To the Heroine Who Directs Killing Intent at Me”

After letting out that bizarre shriek, Kokoa sat back on her heels on the bed as if nothing had happened. No matter how he looked at it, it was far too late for that.

“Onii-chan… Um, school…?”

Kokoa forced the words out. She clearly did not want to ask but could not help herself.

“…Various things happened, so I skipped.”

“Wh-when… from when…?”

“…………”

The intent behind the question was probably when he had started witnessing her odd behavior. He had seen her from the point where she wrapped her body around the body pillow, but he had also overheard her shouting “I love you,” which left him at a loss for how to respond.

Either way, this was no atmosphere in which he could tell the truth.

However, his silence only backfired.

“Ah…”

Air escaped from Kokoa’s mouth. Suddenly, she bounced off the bed as if she had burst.

“Nooooooo!”

With an inhuman scream, Kokoa shot past him like a bullet.

“I got seen, I got seen, I got seen! By Onii-chan…! Onii-chan saw me sniffing his scent like crazyyyyy!”

She ran down the short upstairs hallway, screaming madly all the while.

“Hey! Wait!”

He chased after Kokoa as she descended the stairs.

“I’m gonna die, gonna die, gonna die…! I can’t go on living! Onii-chan thinks I’m a pervert now! He definitely thinks I’m gross…! What do I do, what do I do, what do I do…!”

She clawed at her hair. However, once she reached the living room, Kokoa’s frenzy came to an abrupt halt.

“Ah.”

“Kokoa…?”

“…That’s right.”

Kokoa murmured as if she had suddenly realized something.

Then she dashed straight toward the kitchen.

When he saw her return moments later, he felt utter exasperation from the bottom of his heart.

“Hey, come on…”

The gleaming silver blade. Kokoa gripped a kitchen knife in her right hand.

Why did he have to face a blade twice in such a short time…?

And from two different women, no less.

“I have no choice but to do it now…”

“Kokoa, let’s calm down first. Okay? We can talk it out and understand each other… So for starters, put down that dangerous thing…”

He spoke to her in a soothing tone, but his persuasion apparently did not get through.

“I’m going to kill Onii-chan and then die too.”

“Why does it have to come to that…!”

“That’s right. That way, I won’t have to hand Onii-chan over to those weird women. Onii-chan will be all mine. Let’s die together? Okay?”

“So calm down!”

He kept trying to persuade her, but his words still did not reach her.

Her eyes, with the light gone from them, fixed on him.

And Kokoa advanced straight toward him, kitchen knife pointed in his direction.

Eh… This had to be a joke, right…?

That was the natural thought of any modern person, but when he saw her footsteps, completely unhesitating, he realized he was wrong.

—She was serious.

“Whoa…!”

He kicked off the floor and barely dodged her charge at the last second. A silver flash streaked through the space where he had just stood.

With a thud, the kitchen knife plunged into the back of the sofa. If he had been even a moment slower to evade, there might have been a hole in his abdomen.

This is bad… Bad bad bad…!

Even Senior Yami had not tried to kill him…!

He had to do something before Kokoa could pull the knife free.

“Seriously, calm down…!”

He immediately circled behind her and pinned her arms in a full nelson hold.

“Let go! Let me go, Onii-chan…!”

“Enough already…!”

Kokoa thrashed to escape the restraint.

What incredible strength… Was this that fool’s strength in a crisis…?

Even with the difference in their body weights, this would turn into a war of attrition if it kept up.

“I can’t go on living after he saw that…! I can never become Onii-chan’s bride now…!”

“Gh…!”

While pinning Kokoa down, he desperately racked his brains.

What should he do? How could he break out of this situation?

Reason did not work on a woman who had lost it. He thought he understood that better than anyone.

The effective way to handle someone like this was…

In that instant, he recalled what had happened earlier.

Senior Yami. The bribe had worked on the deranged Senior Yami.

So what about Kokoa?

If he gave her the sweetness she craved more than anything right now, at least this moment—

“No no no! It’s embarrassing! I want to die! Let go, Onii-chan…!”

He had no time to think. For the sake of not getting killed, it was now or never.

“Got it! I get it, so… I’ll sleep next to you…!”

“Huh!?”

Ah, it worked. No doubt about it, it worked.

He decided to press the advantage relentlessly. He would pinpoint what she had wanted in his room and strike at that desire directly.

“You can squeeze me too! The scent…! You can sniff the scent as much as you want! So stop bringing up scary stuff like killing or dying…!”

The resistance ceased completely. When he cautiously loosened the hold, Kokoa slowly turned to face him.

“R-really…? You… squeezing me… and sleeping next to me too…?”

He felt a powerful sense of déjà vu. It was exactly the same face Senior Yami had made when he proposed the hug.

Sadly, his little sister turned out to be cut from the same cloth as that one…

For now, though, he wanted to get Kokoa away from the kitchen knife as quickly as possible.

“Let’s go back to the room for now! Okay? We’ll need a bed to sleep next to each other…!?”

“Uh… Yeah…”

As if her frenzy from moments ago had been a lie, Kokoa nodded bashfully.

With him pulling her by the arm, the two of them returned to his room on the second floor. He decided to ignore the kitchen knife still embedded in the sofa.

He entered the room. When he sat on the edge of the bed, Kokoa settled down primly beside him.

“…Really, I can squeeze you?”

“Y-yeah… So no more bringing out blades—”

It happened before he could finish speaking.

“Onii-chaaaan♡♡♡♡♡♡♡♡”

Kokoa threw herself at him, entrusting her full weight to the motion. He tumbled backward onto the bed.

“Ahaha, ahaha♡♡♡ Onii-chan’s scent…♡♡♡ The real Onii-chan’s scent yessss♡♡♡”

As she rubbed her cheek against his chest, Kokoa inhaled deeply over and over.

“I’ve wanted to do this forever…♡ I’ve always wanted Onii-chan to hold me like this…♡”

If he ignored the circumstances and just considered how she clung to him with her whole body and soul, he would think it was cute. But he could not forget the madness from just minutes ago, when she had swung the kitchen knife around.

In a state of resignation, he gently wrapped his arm around Kokoa’s back.

Between Senior Yami and this time with Kokoa, he had the sensation that his own body was sinking into a bottomless swamp.

Giving sweetness to these deranged women to maintain a temporary peace—this kind of life could not last long. It was like piling dynamite onto a bomb guaranteed to explode someday.

When that time came, what on earth was he supposed to do…?
