mygo, Villain Simulator

As for whether this guide is actually a guide to improving your relationship with your younger brother?

The girl had no doubts whatsoever.

So every night before going to sleep, the brown-haired girl would stand in front of the door, gently knock on it, and then say something.

Goodnight, Wakaba-kun.

At first, she was shy and unaccustomed to it, but as time went on, Nagasaki Sase gradually adapted to the rhythm.

She no longer agonized over the embarrassment of speaking, nor did she rush back to her room immediately after finishing her sentence. Instead, she habitually stood at the door for a while, waiting to hear the somewhat slow but undeniably present response from inside—"Goodnight."

This reassured Nagasaki Sase.

Since her parents' divorce, she had almost forgotten what it felt like to have family.

Now, for the first time, Nagasaki Sase, who was used to this kind of thing, did not receive a response from the room.

Although this habit only lasted for a little over a week.

[Is she asleep or has something happened?]

A sudden unease crept into Nagasaki Sase's heart. She raised her hand and knocked on the door a few more times, this time with more force, her knuckles striking the wooden door with a slightly hurried sound. But there was still no response from inside; the silence was unsettling.

It was so quiet it didn't seem like anyone was there.

Why is there no response?

Nagasaki Sase thought of a similar scene from a recent TV drama—her family knocked on the door as usual, received no response, assumed the person was asleep, and left them alone. But the next morning, they found the door still locked, and the person inside was already…

No, it can't be, it's just a coincidence...

Nagasaki Sase tried to tell herself that Ichinose Wakaba might be wearing headphones or already asleep, but the unease in her heart spread rapidly like vines.

However, this thought did not reassure her; instead, it made Nagasaki Sase break out in a cold sweat, and she couldn't help but breathe softly.

She's not the kind of person who's easily influenced by TV dramas, but recently, based on Nagasaki Sase's observation of her younger brother—Wakaba-kun's condition is indeed not very good.

He spoke even less than usual, was always absent-minded during meals, and looked somewhat tired. Despite being told not to go to work, he continued to do so.

Also, the mother's words: "Souze, Wakaba-kun's health is not very good. The director of the orphanage said that when he was abandoned at the orphanage, he was sent to the emergency room and almost died. So you have to take good care of him, even though you are the younger sister."

All of this felt like invisible threads, tangling around Nagasaki Sase's heart, making her increasingly uneasy.

She took a deep breath, suppressing the ominous premonition in her heart, and knocked on the door again, this time with more force than before, with a hint of urgency: "Wakaba-kun? Are you there?"

Still no response.

The silence inside the room was like an invisible wall, isolating Nagasaki Sase from the outside world and making her heart pound.

No, I need to confirm this.

Nagasaki Sase gritted his teeth, gripped the doorknob, hesitated for a moment, and then suddenly turned it—the door wouldn't open.

It's locked out!

It's impossible for Nagasaki Sase not to be hurt by Ichinose Wakaba's act of locking the door from the inside. After all, she cared for him like a younger brother, but he was so wary of her.

This feeling of being isolated made Nagasaki Sase's heart sink slightly—they haven't accepted me as family yet?

The sudden reality made the brown-haired girl's heart clench, as if something sharp had pierced her most vulnerable spot.

The cold, hard feel of the door lock travels through your fingertips to your heart.

But upon closer reflection, Nagasaki Sase realized that he was no different.

She also habitually locks the door, separating her little world from the outside world.

Thinking of this, Nagasaki Sosei took a deep breath, trying to suppress the complex emotions in her heart. She didn't want these emotions to affect her care for Ichinose Wakaba, and she didn't want to distance herself from him because of it—since she couldn't break down Wakaba-kun's defenses all at once, she would take it slowly.

Thinking of this, Nagasaki Sase felt her unease grow rapidly, as if an invisible hand was gripping her heart, making her breathing quicken.

The brown-haired girl turned and hurried back to her room, her gaze sweeping over the bookshelf before finally settling on a small, inconspicuous box. She reached for it, picked it up, and opened it. Inside lay a silver key.

This key was secretly duplicated by Nagasaki Sase.

When Ichinose Wakaba moved in, Nagasaki's mother gave him all the keys to his room, without even keeping a spare.

Originally, this was nothing to worry about, but because of the dream, Nagasaki Sose secretly made a new one and carefully hid it away.

At that moment, the girl held the key tightly, glad she had made that decision.

She took a deep breath, trying to calm herself down, and returned to Ichinose Wakaba's door. The door was still tightly closed, and there was no sound coming from inside; the silence was unsettling.

Nagasaki Sase raised his hand and gently knocked on the door.

"...Wakaba?"

The girl was met with silence once again.

She frowned, then raised her hand and knocked a few more times, this time a little harder than before, her tone tinged with worry: "I'm coming in, okay?"

However, there was still no sound coming from behind the door.

Silence spread like a tide, quietly filling the entire corridor and causing a tightness in people's hearts.

Thinking of the plot of that TV series, Nagasaki Sase bit her lip and slowly placed her palm on the door. The girl could feel the temperature behind the door, but she could not sense the condition of the person inside.

She hesitated for a moment, but ultimately made her decision.

My fingertips trembled slightly as I inserted the key into the lock and turned it gently—

"Click."

The moment the door lock was unlocked, Nagasaki Sase's heart raced, and he tightened his grip on the doorknob.

I hope... I'm just overthinking it.

With that thought in mind, she took a deep breath and slowly turned the doorknob.

Chapter 84 I actually... (Unclear meaning - possibly a reference to a person's body)

With a "click," the wooden door opened.

What appeared in Nagasaki Sosei's worried gaze was Ichinose Wakaba, who had also opened the bathroom door from her room—Ah!!!

A scream came from the brown-haired girl's mouth. For Nagasaki Sase, who was raised as a noble girl and lived in an all-girls school, the sudden appearance of a male was too stimulating.

Screaming, eyes closed, and turning away, Nagasaki Sase covered her eyes: "Wakawa-kun, if you're here, answer me!!!"

Because of this sudden stimulation, her voice, which she usually suppressed, returned to its original tone, giving Ichinose Wakaba a real feeling—this was the taste.

In Nagasaki Sosei's life simulation, every time she lectures the other person, the cute, pinching voice always makes Ichinose Wakaba feel uneasy.

On one occasion, because of something too outrageous—"Does Sosuke want to be with Shoko?"—Nagasaki Sosuke, with her true voice, gave Ichinose Wakaba a different feeling.

The actress, feigning a moment of surprise, then rushed over from her old place, wrapping her wet body in a towel.

Just as Nagasaki Sase inserted the key into the door, Ichinose Wakaba climbed up the outer wall.

His purple physique, white magic, and golden killer attribute allow him to perform wall-climbing feats like Spider-Man.

Of course, as a consequence, Ichinose Wakaba, who did not enter through the main entrance, could only pretend to have just finished taking a bath when her sister barged in.

[I was almost discovered that I wasn't in my room.]

While not being in the room could be explained by simply going out, doing so would only deepen Nagasaki Sase's suspicions—do you know how uncomfortable it is for me to be watched by her every day?!

If time could be turned back, Ichinose Wakaba would never have agreed to Nagasaki's mother's adoption.

During his week or so at the Nagasaki residence, Ichinose Wakaba had a very unpleasant time. He couldn't do anything because Nagasaki Sosei, the Tsuki no Mori agent, never took his eyes off him.

Just as Nagasaki Sosei felt that what she did was nothing, just an older sister's concern for her younger brother, but to Ichinose Wakaba—it was surveillance.

Therefore, Ichinose Wakaba had no choice but to take this action to avoid giving herself away.

Faced with his younger brother's "I'm sorry, I'll be more careful next time," Nagasaki Saseya, who had finally calmed down, also apologized softly.

Looking back now, my guess was really outrageous.

Although the tension and anxiety at the time were real, now that she has calmed down, Nagasaki Sase is left with nothing but embarrassment and awkwardness.

It's so embarrassing...

The brown-haired girl didn't dare look at Ichinose Wakaba's expression; she only felt the air in the room become scorching hot.

After a few seconds of silence, Nagasaki Sase suddenly raised his hand to cover his face and muttered under his breath, "...I...I want to go back!"

Then, as if fleeing something, she rushed out of the room without looking back.

Her steps were unsteady, her heels clicking rapidly on the wooden floor, and her cheeks were burning hot, as if steam were about to rise from them.

The brown-haired girl slammed her bedroom door shut, so hard that the door shook violently.

"...Ahhhhhh!"

Nagasaki Sase groaned silently as he slid slowly down the door to the floor, covering his face with his hands to try and stop himself from thinking about the incredibly embarrassing scene that had just happened.

Even so, she couldn't help but recall Ichinose Wakaba's hesitant "I'm sorry," and her brother's slightly widened eyes as she fled in a panic.

and also--

That body wasn't completely covered by the bath towel.

The strong muscle lines, the tight abdominal contours... Although it was only a fleeting image, it was deeply etched into Nagasaki Sase's mind like a brand, and he could not shake it off.

[…So strong.]

【Wait! What am I thinking?!】

Nagasaki Sase suddenly clutched her head, wishing she could bury herself in her knees and curl up into a ball, as if that would banish those shameful images from her mind. But her head felt like it was filled with water; no matter how much she shook it, she couldn't shake off those blush-inducing scenes.

Her face continued to heat up, so hot that she could almost hear her own heartbeat. It was as red as a ripe ruby, and even the tips of her ears were burning red.

Nagasaki Sase felt that his sanity was about to burn out.

She wasn't unfamiliar with male bodies; they were everywhere in magazines and on television. She had seen the perfect physiques of various fitness models and celebrities, but those were ultimately illusory, separated from reality by a screen.

Just now, she truly faced reality head-on.

Moreover, compared to the deliberately posed male models in those magazines that Tsukimori's classmates circulated privately, Ichinose Wakaba's body was clearly more realistic.

Even more tempting.

Nagasaki Sasuke knocked on the door as an "older sister," and she entered because she was worried about the other person, but the result was—

So what did she actually do?!

The brown-haired girl let out a weak sob, leaning limply against the door, her hands tightly covering her face, trying to hide her cheeks that were already red and almost bleeding.

Although she was so ashamed she wanted to disappear into a hole, Nagasaki Sase secretly breathed a sigh of relief.

At least, Ichinose Wakaba didn't encounter any accidents as she had feared.

I simply didn't hear her knocking because I was taking a shower.

Instead of being unable to respond due to an illness, as depicted in TV dramas.

Nagasaki Sase sighed softly, trying to comfort herself, but her heart was still pounding uncontrollably, and the heat on her face lingered.

Even though she tried desperately to calm herself down, the images kept replaying in her mind—those firm muscles adorned with water droplets, the smooth lines of her collarbone, and Ichinose Wakaba's bewildered eyes…

Nagasaki Sase's heart was beating faster and faster, and he could even hear the pounding in his chest, the rhythm completely out of control.

What is this?! What is this?!

[I'm his older sister! How could an older sister have such strange thoughts about her younger brother's body?!]

The body, accustomed to its upbringing, stirred once more upon seeing its owner. Meanwhile, the body's actual owner, mistaking this for adolescent restlessness, felt uneasy and shy.

[No, I wasn't thinking anything strange, was I? I was just concerned about Wakaba-kun's health, just a simple observation. Yes, I was impressed that his physique was better than I expected. Mom, really, always saying Wakaba-kun's health wasn't good, but isn't this great?!]

Thinking of this, Nagasaki Sase couldn't help but bury her face even deeper.

She took a deep breath, forcing herself not to relive the shocking scene from just moments ago. But as Nagasaki Sase struggled to lift her head, trying to gather her thoughts, she suddenly heard Ichinose Wakaba's hesitant voice echo in her ears—

"……sorry."

Even though Ichinose Wakaba was the one who was suddenly interrupted, he ended up apologizing.

Nagasaki Sase was stunned for a moment, his heart filled with a complex mix of emotions, a feeling he couldn't quite put his finger on—whether it was guilt or something else entirely.

She recalled the scene from earlier; her younger brother's face had also turned slightly red, and he looked so helpless.

It doesn't seem like a simple dilemma, but rather more like—shyness?

The moment the thought crossed his mind, Nagasaki Sase's face turned even redder.

She covered her face, curled up into a ball, and whispered through her fingers, "...How am I supposed to face him as his older sister from now on..."
