What should I do if I became a tsundere overnight?

Chapter two - my new life (apparently)

When I entered the lounge, I saw multiple banners welcoming the new teacher. And that's- that's reasonable since they started today.

What I don't understand is that they gave the welcome card without me (it was now 07:18 am since I also read a bit more about my apperant "saving" yesterday. ....and I read the whole newspaper to waste some time)

"Hey! What are you guys doing? I haven't signed the welcoming card."

"Who are y- oh my god! Aren't you the girl who stopped the robbery yesterday?! Why- why are you here? You don't work here." Crystal explained.

"What? No, I work here! I left just around five yesterday since i had tests to grade!"

"Mmm.. nope, I did not see you yesterday, did anyone else?" Thomas replied, as roughly as usual.
No, no no, much nicer than usual.

"Now if you don't mind, we have to welcome someone." He continued.

"What are you guys talking about?" Jasmine asked as she entered the room holding a cup of coffee. That just made my day even weirder since she hates coffee.

"Why is everyone so weird? Crystal isn't a stuck up brat, Thomas actually thought about the tone and now Jasmine is drinking coffee?! What has happened?!" I surprised myself with the volume of my voice. I suppose I was worried that since everyone else had seemingly changed, our sweet and kind Jasmine would also be gone, just like my knowledge about the situation was at the moment.

"Why are you yelling? A-and how do you know our names..?" Angela questioned.

"Because I. work. here! And I am not having my record of absence ruined by you guys pulling some weird ass joke on me! Just don't drag Jasmine into it next time!"

"What do you mean "drag"?" Jasmine answered in a tone I never thought I would hear from HER.

"And what do you mean joke? We don't even know you, lady! Listen, we're honoured to have a newly found celebrity at our school, but if anyone, you're the one pulling a prank!" Angela said, defending(?!) everyone.

"I- I wouldn't pull a prank, nor tell a simple joke with out knowing you guys would be okay with it."

"Okay weirdo! Thank you for stopping a robbery, now shoo!" Jasmine said, earning her a light smack in the back of her head from the new teacher.

"You can't just say that to her!" She practically hissed at Jasmine.

I couldn't take more of this and just left the room in a hurry, feeling sad for the first time in weeks.

I still could not piece together how this whole thing happened. I had a normal day and I did not even wish for a "new" or "more exciting" life, but no, that just happens in movies. So that wouldn't be the case even if I had wished for it.

I kept pondering over everything as I left the school grounds, starting to believe that this wasn't some stupid prank, somehow.

When I got back to my apartment I just hopped onto my bed and continued trying to put the pieces together.

I pulled out my thinking hat and started theorizing.

Obviously something weird has happened, whether it's a blessing, nightmare, wish I didn't know I had and so on. After 15 minutes, I found myself settling between the following theories:

1. whether it's a prank or not is super unclear. But, how would my colleagues get the NEWS in on it?

2. it happened after I fell asleep last night and it went unnoticed for everyone except me (if it even was some world swapping thing, which I highly doubt)

"But what if..." I mumbled to myself, starting to question every thing explained by science.

"No." I shook off those ridiculous thoughts and looked at the time. Normally, I would be in a class at the moment, though it still felt right to leave the school grounds, in a weird way..

A few hours later I was reading a book on my couch and was caught off guard by hearing something coming from the kitchen.

It was faint at first and I didn't really think much of it.
But then it got closer and closer by each passing second. It sounded like two people walking. I put my book on the coffee table and sighed in exasperation before flipping onto my side to fake being asleep.

At this point I wasn't as shocked as I would've been on a normal day, with no weird interactions with my colleagues, no fake news, just- my life.

By the time the door that led out from the kitchen and into the living room had started to slowly open, I had laid down and was facing the couch's "back".

I had to get my shit together and stop looking so pissed so me sleeping woule actually be possible to pull off since two strangers had broken into my apartment and are here to do... something..

And unless it's Jasmine they're probably not here for a friendly chat. But Jasmine was probably at home. So that could not have been the case.

I closed my eyes and tried to listen to the movements. There was a small sigh of relief and then I heard whispers, I could hear movements very well but whispering was just not my area so I didn't know what to expect.

To my surprise, I heard someone crouch beside me and I could feel the person's eyes on me whilst i felt another pair looking at me repeatedly with uneven breaks.

"From what I see, our angel is sleeping" I could hear the person beside me say in a low and soft voice.

"She has deceived people before. We can't know for sure if the goddess in front of us is just acting due to you being too loud and eager for this" I heard a stern and irritated voice say from at the end of my bed.

I vaguely recognized that voice, but I just couldn't place my finger on it.

"Easily fixed. Sedative is such a life saver sometimes, right?" The voice beside me replied.

"Yeah yeah, just hurry up. I don't want any creep other than you looking at her." The person on the other side of my couch said as sternly as before.

When she was done berating her partner in crime, I could hear an annoyed sigh from the person beside me and I had a feeling that she wanted to start a scold the other person right back. Though she didn't, incase I actually was asleep.

After that I could barely hear their voices. They kept getting further and further away yet I still felt them looking at me. They had used the sedative.
