Until My Spirit Was Destroyed By My Super Yandere Childhood Friend And I Fell Into Darkness - Chapter 4 (It's all Kaito-kun's fault that I became like this)

It’s all Kaito-kun’s fault that I became like this

“Sorry to make you wait. Were you waiting too long?”

“I see. Well, that’s good to know.”

When I arrived at the shoebox, I apologized to Ellen, who would have been here first, for making her wait, she responded with a beautiful smile and a slight laugh.

And we changed from our slippers to our shoes and lined up like usual and started to go home.

“Speaking of which, you seem to be running later than usual today, did something happen in the classroom?”

“Yeah, I had a classmate who suddenly asked me to help him/her study.”

Ellen asked me why, and since I had no particular reason to hide it, I answered normally.

Ellen then became interested and asked a question.

“I see. By the way, who was it that asked you to teach him/her?”

“I don’t know if Ellen knows him/her or not, but it’s a girl named Minase-san.”

“…… Oh, that gal-looking girl. I’m a little surprised because I had an image that she didn’t seem to study at all.”

Ellen was silent for a moment with a blank expression on her face, then quickly returned to her usual tone and began to speak.

I had assumed that Ellen did not know about Minase-san, but from what I heard, it seemed that she did.

Ellen had a wide circle of friends, so perhaps there was some connection.

“I have to admit, I was pretty surprised too, but she seemed to be in a lot of trouble, so I decided to teach her.”

“If Kaito-kun, who is ranked first in our grade, is teaching, her grades are likely to improve. Well, if she’s willing to do it.”

“She seemed pretty desperate, and I’m sure she’ll do her best.”

We were slowly making our way home, talking about such things, when I gradually began to feel uncomfortable with Ellen walking next to me.

At a glance, she looked no different from the usual Ellen, but since a while ago, I had been feeling something that I couldn’t describe in words.

What exactly is this feeling of discomfort?

“Hey, Kaito-kun. Why did you suddenly become silent?”

“…… Oh, sorry. I was just thinking about something.”

I returned to my senses when Ellen spoke to me and hurriedly apologized.

It seemed that before I knew it, I was in a world of my own.

I was still feeling uncomfortable, but I couldn’t figure it out, so I decided not to worry about it.

We then walked around chatting appropriately for a while and arrived in front of Ellen’s house, so we parted there as usual.

Then I start walking toward home, simulating in my mind how I will teach Minase-san in the future.

“I wonder how I can teach Mizuse-san how to study……I don’t know what level you’re at now to begin with, so let’s just make a simple test to see how good she is.”

I will need to think carefully about how to teach Minase-san in the future.

“…Did I behave as usual?”

Once inside the house after leaving Kaito-kun, I sat down on the floor of the entrance hallway, unable to bear the fatigue as I spoke.

The act of pushing down my anger and acting my normal self was harder than I thought it would be.

Perhaps he might have felt some kind of discomfort from me, but he would not have noticed it until I was angry.

“……I honestly didn’t expect the next one to show up so soon, even though I just had Alan get rid of a woman who was getting in the way.”

Needless to say, the cause of my anger had to do with a woman who is a classmate of Kaito-kun’s named Yuki Minase.

It is unforgivable for a woman other than myself to be intimate with Kaito-kun, and yet, here we were, alone together, studying.

I am going crazy with jealousy, and I really want to prevent it beforehand, but I have to be patient now for the sake of my plan to make Kaito-kun mine and mine alone.

I plan to have Alan corrupt her at the right time when Kaito-kun starts to care about that woman.

Although I hate Alan from the bottom of my heart, he is very popular with women anyway, so he is a very useful brother only at times like this.

Alan can never disobey me because I have his weakness and make him follow me.

I will continue to use Alan to push Kaito-kun mentally to the point where he will become suspicious of people, and on the other hand, I will continue to appeal that I am the only one who is on Kaito-kun’s side.

It will make him believe only in me, the only person in the world who will believe in him.

It will be a little bit painful for Kaito-kun, but that can’t be helped.

This is also essential for the ideal future in which Kaito-kun and I will be bound together.

This is what we call a necessary sacrifice.

“It’s all Kaito-kun’s fault that I became like this. I’m going to make you take responsibility for it.”

I mumbled to myself as I prepared for my daily routine of tailing.
