My Curse? A Different Yandere in Every Reincarnation

"What are you doing awake at this hour, Shizune?" I hear a voice, the tone strangely cold, and I quickly look back to see Himari.

"I-I was thirsty a-and so I got up to have a glass of water." Himari's gaze is strange and even a little disturbing.

"H-Himari, why did you throw away the food and cookies?" I ask, trying to understand why she threw those things away.

"..." She remains silent and soon returns to her usual cheerful self.

"Haha, it's just that while I was getting something from the refrigerator, a cockroach fell on the food, ugh, I got so scared by that, I just shiver just remembering it, so I threw the food and cookies away." This is the normal Himari that I met today.

'W-What was that...w-why did she seem so cold and scary?...' What she said seems plausible since the food would have germs and bacteria, but something makes me think that this is a lie.

"But Shizune, you could have asked me to get water for you, you didn't have to get up and come alone, imagine if you got sick?" She speaks with concern.

'Did I deceive myself? Am I being too paranoid?...it's dark and I just woke up...maybe I just imagined things because of the paranoia I have in this life...' I finish what I had to do in the kitchen while Himari waits for me.

'Why is she so helpful...' I wonder as we go to the bedroom.

'Is it really just paranoia?...what did Sayuri say? Try to remember' I do everything to try to remember, the combination of paranoia and Sayuri's words makes me think about this situation.

'Why did Himari wake up...and why did she come after me?...I'll think about it later...' I go to my bed to sleep.

...

...

I wake up in the morning with a nice smell, and I see that Himari is no longer here and everything is tidied up.

The first thing I think about when I wake up are some disturbing things I remembered about what Sayuri said.

I decide to try to find out if what I think is real, I calmly get up and start looking for Himari's things.

'It's not here, but I know she has a purse somewhere' I leave the room and go to the bathroom to brush my teeth and wash my face, after doing that I start looking for Himari's purse.

After entering some rooms, I finally find the purse she brought with her, the purse was in what I judge to be my mother's room, I open the purse and start rummaging through it.

There are books, a wallet, makeup and her cell phone, which when I try to unlock it, requires a password.

'Was I wrong?...this new body is so paranoid and I'm imagining too much?...'

"I think I was wrong...what's this?" I see a small plastic bag, it's small and transparent, and inside there is some kind of bluish-cyan powder, it seems to have already been used since there are only traces left.

I decide to take it with me, I don't think she'll notice it's missing since she's already used it, she'll probably think she's already thrown it away.

'On the cell phone it was 06:37, according to the diary I usually wake up late...' I remain silent as I go to the kitchen.

"Uh hmm uhhmm uhmmm" I see Himari humming cheerfully around the corner, she's making an omelet and I watch her attentively, I think I'm not just being paranoid.

I managed to remember what Sayuri said, and if it's really what I think, I think Himari is the person who will try to kill me, although in this world I'm very paranoid and my intelligence is obviously reduced, I still have good deductive ability.

In the business field, good deduction is important, and if I'm right, according to what Sayuri said, someone will fall in love with me and that same person will kill me.

And I might know this person or I'll get to know this person, and this person will be responsible for my death, but nothing guarantees that this is really bad, for example I could die saving her instead of her killing me.

If I'm following the logic that I betrayed Sayuri and she got angry and cursed me so that I wouldn't be able to use anyone's love and also learn a lesson from it.

Then the deduction that Himari is the one who will kill me is clear, now what I don't understand is why? If Himari loves me, why would she kill me? Is there something more that I still don't know? What am I missing?

It's impossible to say how I'll die, I just hope I'm wrong and that Himari won't try to kill me.

I soon become slightly shocked to see Himari adding that blue powder to my food.

'...' I decide to go back to the bedroom and wait until it's time to normally wake up.

"..."

And so after waiting a long time, I hear Himari scream.

"SHIZUNEEEE BREAKFAST IS READY YOU SLEEPYHEAD!" I get up from the bed, pretend to go to the bathroom, wait a bit, and go to the kitchen.

"Good morning Himari, the smell of breakfast is great." I look at the breakfast, wondering what she added to the food.

'Is it poison? Is this how she's going to kill me?...or not? After all, there's a little packet that was used and I'm still alive...' I sit down at the kitchen table as Himari serves me breakfast with a smile.

'Was that why she threw that food away? She didn't want to ingest that blue powder? What is that really?...'

I take a bite of the omelet and try it with some trepidation.

"Hmm, it's incredible..." I praise the food as soon as I taste it, this is actually really good, Himari sits down and watches me eat.

'Again...Himari isn't eating...' She just watches me eat, but there's no plate or bowl with food for her.

"Himari, aren't you going to eat? It's delicious," I say while looking at her.

"Haha, I already ate, Shizune, anyway, you have a doctor's note, so you don't have school today, lucky you, today is history class, the history teacher is so boring." She jokes, pouting, but I think she's just trying to change the subject.

So I finish my breakfast while we talk, and after I finish, Himari gets up and says goodbye to me, saying she has to go home to get ready for school.

"Bye, Himari," I say in front of the door.

"Bye, Shizune, call me if you need help," she says, waving cheerfully at me, soon she's no longer visible, I take out my phone and open the GPS, luckily my phone doesn't have a password.

I look for the nearest pharmacy and go there quickly, I'm in casual everyday clothes and haven't even combed my hair properly, so it's a little messy, but I'm still annoyingly beautiful.

After a few minutes, I arrive at the pharmacy, fortunately there's no one there, so I can be served right away.

"Good morning, young lady, can I help you with something?" An old man is at the counter, he seems kind.

"Ah yes, I really need to know something," I don't know if this blue powder is really poison or something like that, and I need to know.

"And what would that be, young lady?" He speaks gently.

"Could you tell me what this blue powder in this little packet is?" The old man takes the packet and looks at it carefully.

"Well...it's hard to say for sure, but I can do a test here, it'll take about 15 minutes, okay?" He says after analyzing the blue powder and not finding anything.

'Test? Here and now?...how modern is this world?' A test that can check a medication in 15 minutes is not something that was possible with the technology of the world I came from.

"Okay, I'll wait, thank you very much...ah...I-I don't have any money..." I think I thanked him too soon, I don't have any way to pay for this.

"Hmm...it's okay, young lady, I'll make an exception." He makes a thoughtful sound and then says with a kind smile.

"Really? Thank you so much," I thank him cheerfully for the unexpected kindness, he soon enters a room that has a sign that says 'Employees Only', and I wait.

I wait about 17 minutes and he soon comes out with a serious expression.

"Young lady, I hope you're not using this, could you tell me where you got these samples?" He speaks in a serious tone.

"I-I'm not...a-a classmate was doing a science project on chemicals and asked me to research this for a school project," I thought of this excuse while waiting, I figured if it was something serious, he would ask about it.

"Whew...good thing you're not ingesting this..." He says as he hands me the plastic bag again.

"And what is this, sir?"

"It's a 'drug' that was once called Grinproloarx, it's currently called 'Prolonged Dream', its use was banned about 20 years ago."

"Initially, it was used as a sedative, as it proved to have great abilities to calm people down, but its use was banned because it causes various side effects."

"W-What kind of...side effects?" I swallow hard.

"Well, single or occasional use doesn't cause anything, but if used for a prolonged period, it causes paranoia, anxiety, addiction, and also makes the person who took it acquire emotional dependence or extreme emotional attachment to people who are close to them."

'Himari...'

"Sir, could one of the effects be that during anxiety attacks the person would quickly calm down if they were near the person they became dependent on?" I ask, hoping he'll say no.

"Correct, young lady, if someone took this for a prolonged period and developed anxiety, the anxiety would be controlled by being close to the person they acquired emotional dependence on."

"..."

"Young lady, are you okay? You look rather pale," He asks worriedly, seeing how I am.

My skin, which is already slightly pale, has practically turned white.

"A-Ah, I-I'm fine...t-thank you for the help..." I run out of the pharmacy as if I'm fleeing.

'My diary said Himari always cooks for me...s-she's been drugging me...for years' I feel tears of despair and fear fall as my anxiety starts again.
