s/b- Sister/Brother
[3rd pov]
After teleporting back to your room, you suddenly felt sick to your stomach and ended up vomiting. The dizziness that followed caused you to lose consciousness, and you barely had enough strength to stand up. You collapsed on the floor and warm tears started running down your cheeks.
When Saiki returned, he hugged you, and you hugged him back, seeking comfort. You both sat on the floor, not moving for a few minutes, with the only sound being your soft sniffles. Saiki then decided to carry you to your bed since you could not stand properly, and he gently laid you down on the soft mattress.
As you lay on the bed, Saiki placed a damp, cold cloth on your forehead. Your entire body felt hot and uncomfortable, and the sensation was different from any other fever you had experienced before. You felt numb and unable to move properly.
"Ku..." you mumble weakly.
"Yes?" Saiki leaning down to your face to get a better hearing.
"I'm... sorry... I don't know that-"
"Yea, I know. Don't worry about it. Just focus on getting better okay?" he murmurs then gently brushing strands of hair upward so it won't distract my face.
You quietly hummed in response.
"Mom is making you food, I'll be here with you." Saiki says, sitting beside you on the bed. Gently patting your head, soothing you.
You both stay silent, secretly enjoying each other company. But got interrupted by a loud door opening sound, revealing Mom and Dad with worried faces.
"Y/n-chan!! Are you okay?!" Mom asked me, looking at me being in a vulnerable situation.
"yea..." you weakly mumble.
Dad kneeling beside the bed in front of me before crying dramatically.
"Y/n... Hang in there with me!"
"they're not dying!" Saiki deadpan.
"Move old man!" Mom demanded before sitting on the bed and then putting the tray on my nightstand.
Mom pulled out a strange-looking bottle of pills. "I got this from a sale. He said if I swallow this, I'll be better instantly from any sickness!" she tells you confidently.
"Mom... That's a rat-repellent pill..."
"Wait really?-" She turns the bottle.
"NO WAY-" Then got struck by lightning.
"Where did you even buy that?.." Saiki sighed.
"Just let me take care of Y/n, you both are too chaotic."
"Are you okay with that?" Dad asked Saiki.
"It's not a hassle at all."
"Well okay then, we let you handle y/n. They're your little s/b after all" Mom said happily, feeling proud that her son taking care of her little siblings.
"Get well soon my baby" Mom and Dad pecked your cheeks
You smile at them ensuring that you will. The parents left your bedroom, closing the door gently.
"I'll feed you, let's get you sit up first," Saiki tells you before helping you sit up slowly with your back lean against the headboard.
Your brother blows the spoonful of porridge to let it cool down a bit before feeding you.
"You know, I can read minds. So just think in your head if you need something." He tells you before feeding you again carefully.
'I don't understand... Why did I teleport? Do I have powers just like you Ku?' You thought on your mind, now is heard by Saiki's mind.
"I have no idea... You don't have to worry about it. I'll always be here with you no matter what."
You look at your now smiling brother, slightly shocked by the mesmerizing smile and so you decide to smile at him back.
"It's rare to see you smile other than something sweet."
"Well you are sweet Y/n, my sweet little s/b."
[Saiki's pov]
I look at my now blushing little s/b. Even a slight compliment can change their mood.
They glanced at me for a second before looking away, staring anywhere but my face.
"Dumbass..." They mumble.
I felt veins popping on my head when I heard her. But I keep it to myself and give a fake smile instead.
After finished feeding them. I help them lay back down on the bed slowly then pull her blanket up. Covering all of their body and half of their face.
"Well, goodnight. If you need anything just knock the wall beside you." I said mono
"Okay, goodnight..." They said.
We stare at each other for a bit. Confused why I'm not moving from my place. I feel like something is missing. When I look at your face that's when I realize what's empty.
I peck your forehead.
"Get well soon..." I mumble before quickly turning off the light then go outside before closing the door gently.
I get back to my room sitting down on my bed with my hand on my reddened face, covering it.
"Am I blushing?.." I mumble quietly to myself before turning the light off and then lying on my bed. Staring at the ceiling while trying to understand the feeling he felt in his stomach.
He has never experienced these feelings with anyone other than Y/n, and he wants to avoid them, but they keep coming back. It's starting to bother him because he knows this is wrong.
'I'm being weird today...'
Bonus:
"Our son is growing up!" Mom dramatically cries with Dad on the bed.
