The Protagonist's Sister Loves Me, But She's Definitely a Yandere. - Chapter 03: This is Basically a Threat Letter

Chapter 03: This is Basically a Threat Letter

“Huh?”

The next morning, still heartbroken, I couldn’t believe my eyes.

I wondered if the trauma of yesterday was making me hallucinate. But no —the letter was definitely there. It made no sense.

After going home yesterday, I had screamed into my pillow more times than I could count. The sheer embarrassment of getting my hopes up. The frustration and helpless anger. I finally forced myself to sleep sometime past midnight. I put a hand to my forehead and shook my head wildly.

“Wait, wait. Wait, wait, wait.”

Why was there another letter in my shoe locker?

Two days in a row. Two days in a row!

I was so confused that my head started to hurt. 

Did the same girl accidentally put another letter in my locker? 

No way. After the awkward disaster yesterday, that seemed pretty unlikely.

Thinking about it, she wasn’t in my class, and she didn’t seem like a second-year. So that left first-years or third-years. Since she didn’t use formal language with me, she was probably a third-year.

Plus, thanks to my unfortunate title as Hinata’s best friend, a lot of people at school knew my face. But she didn’t recognize me. That made it even less likely she was a classmate.

At my school, every shoe locker has a name label. For someone from another grade to slip a letter in during the chaotic morning rush without getting caught, they’d have to be in a hurry. In other words, it wasn’t impossible for someone to make a mistake once.

“It’s… really there.”

I lifted my head and stared at my shoe locker again.

It was there. It existed. A few millimeters thick.

Besides the fact that it seemed unlikely someone would mix up lockers two days in a row, there was another clear reason why this letter couldn’t be from the same girl as yesterday.

“…What’s with this color?”

It was pitch black. Jet black. The kind of black that could blend into the shadows inside the locker.

Unlike yesterday’s soft pink, this one gave off a creepy vibe. Normally, love letters are in pink or red envelopes. But this? Black. It felt more threatening than romantic. It was definitely not a color I would choose to confess my feelings.

I held it up to the sunlight to see if I could peek through it, but no luck. 

The paper was high quality and thick, with a glossy finish. It didn’t match the personality of the girl from yesterday at all.

I thought about it for a few seconds.

“Well, whatever.”

I carefully stuffed the letter into my bag, making sure not to damage it.

Yesterday, I got so excited about my first love letter that I took too long to put it away. This time, I prioritized hiding it in case Hinata or anyone else tried to corner me.

My heart was still beating fast, but after yesterday’s fiasco, I was handling it a little better. I wouldn’t say I was getting used to this —no way.

Though, let’s not forget, yesterday’s love letter wasn’t even meant for me! Damn it!

Frustration started bubbling up again, but I forced it down. 

No one was to blame for what happened. If anything, I should be happy I even got to feel like I was being confessed to.

“Hey, Shinji, morning!”

Just as I was sinking into self-pity, Hinata’s voice rang out.
I looked up and saw Mr. Sparkles himself —Hinata —and Rika walking to school together.
I joined them, and we chatted about random things.

“Hmm…”

After excusing myself from Hinata and Rika, I found myself sitting on a bench in the courtyard.

A cool breeze blew gently, making me feel a little better. But in my hand was that jet-black envelope.

If it had flowers or stars drawn on it, maybe it would feel different. But this letter was plain. Just solid black, front and back. I couldn’t help but think, is this really a love letter?

No, that’s rude of me. The sender must have some reason for choosing this paper. I’m nowhere near popular, so understanding a girl’s feelings is like solving a complex puzzle for me.

I rubbed my chin and thought about it for a good ten seconds. Whatever —I needed to open it.

Maybe, just maybe, this was finally a love letter meant for me.

As soon as that thought crossed my mind, my heart started pounding.

Sweat began to form on my palms. My imagination was running wild again.

“Alright.”

I took a deep breath, steeled myself, and opened the envelope. Inside was a single sheet of paper.

So far, this was just like yesterday. But what really mattered was what it said and who it was from.

Please, let this finally be a love letter for me!

I want to go to the aquarium. I want to go to the zoo. I want to see a planetarium. Please, please, I’m not asking for much —just let me have my springtime romance. Give me a little piece of that sweet, youthful love!

“I know everything about you. I know your favorite foods, your favorite animals. I know everything there is to know about you. I’ve been watching you all this time. No matter where you go or what you do, I’m always watching you. Always, always, always. 

I won’t let you go. I won’t let anyone else have you. You are mine and mine alone. Until death se— no, even if you die, you’ll still belong to me. 

I like you. I love you. I love you so much I want to lock you away. I love you more than anyone else in the world. If you date anyone else, I’ll kill you. You absolutely must not date anyone else.”

―To Shinji Usui-sama.

The handwriting was elegant, almost hypnotically beautiful.

The letter ended with my name. So yes, it was definitely meant for me.

I nodded to myself. Okay, got it —this one was for me.

Right. Sure. Okay. This is…

“A threat letter, isn’t it?!”

It seemed my luck really was terrible.

Yesterday, I got called out by mistake. And today, someone sent me this bizarre thing that might as well be a threat letter.

This was too much. Just way too much.

The sky was annoyingly bright and clear.

And that was how my morning started.
