I, Who Am Somehow Only Liked by Yanderes, Tried Transferring into a Class Full of Yandere Girls

After that, I began to follow Aiji-kun even more closely than before.

It was a necessity.

If Tsukimiya-san were to try to harm Aiji-kun, I had to leap out from the shadows and protect him with my own body.

It was more of a surveillance activity than stalking. A campaign of protective love.

To do that, I had to be constantly by his side…

But even if I were to confront Tsukimiya-san, I doubt I could match her.

Tsukimiya-san, excelling in academics and athletics and incredibly talented, also had outstanding physical abilities. In the last endurance run, she left me two laps behind.

Well, that’s more because I’m too slow…

So, alongside watching over Aiji-kun, I decided to start training.

Yesterday, I managed to do push-ups three times.

Considering that I couldn’t do even one on the first day, and my arms trembled like a newborn fawn before I finally gave out, it was quite an improvement.

With my arms sore from the workout, I watched Aiji-kun from a distance as he diligently worked his part-time job inside a convenience store.

Today, I watched from outside, but sometimes I go inside too.

Thanks to my naturally inconspicuous nature, I can completely erase my presence, so the security cameras might not even capture me.

After finishing the book I brought with me, as the day turned to dusk and Aiji-kun finished his shift, he exited the store from the back door.

I followed him safely until we arrived at an apartment building.

It seems Aiji-kun lives here.

Looking up the property on my smartphone, it appeared to be a singles-only building.

It seems Aiji-kun lives alone. There must be some circumstances for a high school student to live apart from his parents.

I didn’t pry. But I did feel a sense of closeness.

As researchers, my parents often left the house, effectively leaving me living alone.

After ensuring Aiji-kun entered his room, I turned to head home, ending my surveillance for the day.

That’s when it happened.

A female student was walking towards me in the opposite direction.

Under the moonlight, cutting through the darkness, it was Tsukimiya-san approaching.

I immediately hid in the shadow of a utility pole.

She would have noticed me if my reaction had been a few moments slower.

…Why is Tsukimiya-san here?

Tsukimiya-san, looking up at Aiji-kun’s room on the second floor, had a dreamy expression on her face.

Then, moving to a secluded spot, she took something that looked like a receiver out of her school bag and began listening to something with it pressed to her ear.

With utmost caution, I approached Tsukimiya-san.

Sharpening my hearing to its limit, I could hear voices leaking from the receiver.

The words were muffled and indistinct, but I could clearly understand that it was Aiji-kun’s voice.

—A bugging device…

There was no mistake about it.

Tsukimiya-san was eavesdropping on Aiji-kun’s room, intently listening to every little sound and breathing heavily with ecstasy at every word spoken.

So, Tsukimiya-san does have feelings for Aiji-kun…

And she was dangerous, engaging in illegal activities like eavesdropping without any hesitation.

I… I have to protect Aiji-kun…

A few days later.

I waited for a time when Aiji-kun was out and went to check on his apartment. Standing in front of his room, I pulled a detector from my school bag.

It was something I bought online recently.

If there were a bugging device nearby, it would make a sound.

And soon enough, the result was clear.

There was a reaction from a bugging device inside Aiji-kun’s room.

Just as I suspected.

But the problem starts now.

Knowing there’s a bugging device, it must be removed.

How? Should I tell Aiji-kun about it? That might only make him anxious.

—I have to do it myself…

If I, instead of Aiji-kun, could remove the bugging device from his room…

No, no, no. That would be breaking. First of all, I would need the keys.

Unless there were a spare key, such a convenient thing surely wouldn’t be lying around.

But there was.

On a whim, I peeked into the mailbox and found a spare key taped to the inside of the lid.

I could enter the room.

“……..”

—Just a little bit. I’m only intruding a little bit. It’s necessary to protect Aiji-kun’s privacy.

With resolve, I inserted the spare key into the lock.

As the door opened, I timidly stepped inside.

“…Excuse me.”

Not that saying so makes breaking more permissible, but my inherent timidity was fully displayed.

The room was a ten-tatami mat one-room apartment.

Immediately inside the entrance was the bathroom leading to the bath, next to it a door to the toilet, and the bedroom was down the hall with the kitchen.

There was a sofa, a rectangular table, a TV, and by the window, a bed, a study desk, and a bookshelf.

This… This is Aiji-kun’s room…

Entering a boy’s room for the first time, I was nervous.

And I couldn’t help but peek at his bookshelf.

As a book lover, the contents of someone else’s bookshelf pique my curiosity.

There were light novels, literary books, mysteries, and manga.

There was also a book I had given him, placed quite prominently on the upper shelf.

“I can’t help but grin…”

Without realizing it, my face broke into a smile.

Aiji-kun had told me before that he disposes of books he didn’t particularly enjoy once his bookshelf becomes too full.

The fact that he kept my recommendation means he must have liked it.

As the one who recommended it, there’s no greater joy than this.

There were also some books that I hadn’t read yet. I plan to read them next time. I want to know Aiji-kun’s tastes.

“…Right, I need to search for the bugging device.”

This is no time for such distractions.

My goal is to search for the bugging device.

Taking out the detector, I walked around the room thoroughly. As a result, I found a spot where the reaction was strong.

A triple outlet.

This must be it.

I took out an identical outlet that I had brought with me.

Thinking that an outlet would be a likely choice for planting a bugging device, I had ordered several different types in advance.

I replaced the outlet with the one I bought.

“…Phew.”

I completed my mission.

Now, Aiji-kun’s privacy is protected.

If Tsukimiya-san realizes that the bugging device has been removed, she’ll probably become more cautious and won’t act recklessly anymore. Probably.

Now, let’s make a quick retreat.

Just as I was about to head to the entrance—right at that moment…

Click.

“…Eek!?”

I heard the sound of the lock being unlocked.

In that instant, my heart nearly leaped out of my mouth.

—What? What? What?

My mind was in a state of confusion.

—How could this happen!?

Aiji-kun was supposed to be out with friends. I heard him talking about going to karaoke in the classroom.

He wasn’t supposed to come home at this time…

A terrifying thought crossed my mind.

Could it be Tsukimiya-san…!?

—I need to escape, no matter what.

Whether it’s Aiji-kun or Tsukimiya-san, they shouldn’t find out I’m in this room.

Escaping through the balcony is not an option with a visitor at the entrance and the fact that this is the second floor.

If someone in the neighborhood were to see me jumping down, it would be terrible.

Besides, with my poor athleticism, I will likely land poorly and end up squatting on the street with a broken leg.

In a panic, I looked for a place to hide and opened the closet in the bedroom. I squeezed myself into an empty space next to a chest of drawers filled with clothes.
