Yandere! Younger Brother & Reader (Older Sister)

Wretched

I love my readers and commenters sooooo much! <3 I just want to squeeze y'all to death! (But I won't, cuz I tend to hurt people when I do that) Almost 70,000 reads, I might fall down the stairs thinking about it.
I believe I might make a writing draft story, so then you can either peek on the ideas I did have for this story and forge it into something,  or just see the original copies. However, I'm up if you would like it!

Atleast at school you could escape him. You sighed hauling yourself into the classroom. Roy still hadn't come back to school, so it was just you, Kiriyu, and Arthur.
You walked to your desk glaring as the morning light seeped through the lazily closed blinds. It illuminated you as you scrunched your muscles in dread.
"Geez, your even more dead today!" Kiriyu clicked his tongue, hurtling back in his chair at the sight of you.
You didn't bother dressing normally or even fixing your hair in a less vulgar appearance. There were bags under your eyes and there was possibly still vomit stuck to you face. If not, you sure did reek of it!
Arthur batted the stench approaching his flared nostrils. He viewed you, cringing slightly due to your acid looks.
"M'lady, bless the queen, what happened to you!?" You shrugged sitting down and laying your head flatly on your desk.
"I died." You hoarsely spoke. Kiriyu squinted with furrowed bros.
"You sound hideous! " He retorted bluntly.
"I feel horrendous, but that's life." You coughed a bit.
"Dude, you must be sick!" He raised a palm to forehead, stammering at the touch.
"Your burning up! " You shook you head, removing his cool palm off you head.
"I'll be fine-"
"I'm taking you to the nurse's office! " Kiriyu stood up and grabbed your hand. He waved at the teacher, who was just settling at the front of the classroom.
"Miss, she needs to go to the nurse." He stated, tugging you out of your chair.
" "I'll come along!" Arthur invited himself, but you had already dissappear out the door.

Kiriyu rushed through hallways, making sharping turns every once in a while almost forcing you into the corner of a wall. When you finally came to a halt in front of the Nurse's office you panted heavily.
"Kiriyu, I'm fine really-"
"No you're not; stop lying!" He shoved his grip on your hand again, and pulled you along into the room.
The nurse was nowhere to be found. Empty silence filled the room, causing you to cough out your awkwardness.
"Of course she's out, here take this." Kiriyu spun around, slipping a thermometer through your parted lips.
"Mmph!" You gagged at the sudden movement. A couple seconds passed and he took the thermometer from you.
"103F°, where'd this fever come from?" Kiriyu stepped back, spinning around to observe a shelf off to the side in the office. He fumbled around some antibiotics,  before pulling out Tylenol amongst them.
"I'm not sure what to give you so here." He offered a small pink pill.
"Though, this is kinda breaking the rules because I basically just offered you drugs ... hehehe ... no." You popped the medicine in your mouth, swalling it immediately. It slowly bobbed down your scratchy throat.
"So, what happened? " Kiriyu sat down on a bed. Hands on knees, he looked below respectively.
"Saiyo was there." Your voice cracked a little, but you continued.
"I had just made it home and was sitting in front of the entrance to my room. Then there he was. Standing behind the door. Tracing, finger nails, I guess, against the wood?" Your stomach bubbled.
"It's not safe to be there anymore. You have to leave!" Kiriyu clenched his fists.
"I have no where else to go. You know we don't have parents or relatives." It hit you like a brick wall.
"But you have me! I can't sit and watch idly as you are being tortured by your own kin. (Y/N), stay with me!" A tear rumbled out of his eye.
"You can live with me until then. Just don't say you'll stay in that unhealthy environment!" Kiriyu jumped up, embracing you with his arms. You stumbled, faltering due to how weak you've become in the last twenty-four hours.
"Kiriyu-"
"I won't take no for answer!" He rasped into your ear. And like that, he dragged away from the school campus.
