[HIATUS] Will You Stay By Me? levi X Reader. Highschool AU

At school once more

After you finally got out of bed, you and Levi slowly made your way to school.
"Why is there such thing as school?"
"I don't even know (y/n). I would skip it with you but we would get caught and in trouble. Let's make the most of it, ok?"
You looked at Levi and saw he was trying to make the best of the situation. You decided to make it easier for him.
"Ok Levi!" You grabbed his hand and struck up a random conversation.
*Levi's pov*
Why is she suddenly so enthusiastic?  Meh, as long as she's happy I'm happy.
Finally we arrived at school, but there was no one there. Something seems off. I didn't know why, but I put (y/n) into my arms, just in case.
"Levi?" (Y/n) asked, fear in her voice
"What's wrong?"
"It's Petra..."
Shit. I looked up from (y/n)'s face to see Petra standing there, grinning like the psychopath she is, holding a knife covered in dark red blood. Her hair and clothes are soaked in blood too. In instant, I realized that she killed someone. Not just someone, but possibly the whole school.
'She must be a Yandere' I thought. A yandere is the name for someone who who loves someone so much and will eliminate anyone who stands in the way of their loved one and themselves. In this case, she killed possibly the whole school to make (y/n) lose her strength, then she will eliminate her. Then she will try and make me love her. Fuck no. If she kills (y/n), my life is shattered.
"Petra, why are you doing this?" (Y/n) asked, pain in her voice. She must have figured out what she's doing.
"You know why. Levi is the love of my life. We've been friends since kids, I always looked up to him, hoping that one day he would return my feeling for him. Then you come. I saw he made friends with you quite quickly, but I thought he would prefer me because we knew each other longer. But what do you? You shatter my dreams. In front of me."
(Y/n) was on the verge of crying and I would NOT let that happen. I let go of (y/n) and

(Y/n) Pov:

Levi let go of me and walked towards Petra. Please be okay Levi. You're the strongest man on Earth apparently, prove it. Levi flew a punch that was so fast, neither me or Petra expected it. It landed in the middle of her face, causing a crunching sound. Probably her nose.
She toppled back, causing her knife to go scattering on the floor, right next to my foot. Levi held her down and shouted, "(y/n)! Get the knife!"
I instantly picked it up and Petra suddenly broke free. I held it directly in front of me as she charged in my direction. She realized what would happen if she didn't stop running so tried stopping but at the speed she went, she was failing. Unfortunately, she stopped right in front of the knife and grinned deviously.
"Oops looks like you-"
She stopped mid sentence and dropped to the ground, blood pouring out of her head. I looked up to see Levi with a massive rock covered in blood. He was breathing in and out.
"Is there an incinerator in the school?" He asked. Why would he want an incinerator? Oh yeeeeeah! To burn the rock and knife since it has our fingerprints! The knife had Petra's fingerprints but since I held it as well, I could be arrested and we don't want that do we?
"Follow me." I said and ran to the back of the school with Levi behind me.
Levi's  Pov:
We finally found the incinerator and dumped both the knife and the rock, and turned it on. Luckily our clothes had no blood. (Y/n) ran into the school building and opened a room door. (Y/n)'s eyes widened at the ain't she saw inside the room and burst out crying. Could it be that bad? I decided to take a look myself, and I instantly regretted it.
Everyone in the school, was locked up to each other, gagged mouths and cuts all over their body. Both me and (y/n) ran to undo the knots and untie their gags. I kept hearing (y/n) whispering the word why over and over.

LE TIMESKIP!

After me (y/n) saved everyone, the head teacher allowed us all to go home. He acted like he was doing us a favour like what the fuck? I went to my house with (y/n)  since her family is away and she just encountered a horrible experience. I need to be by her side so she feels at ease.
