Asahi's sister (Tsukishima X reader)

Fire + fire

Y/n

"Your fart stinks!"

"Your breath reeks!"

You and Tsukishima were in the gym fighting once more during warm down. You were helping to pick up the balls to put them back in the basket and Hinata and Kageyama were behind you still practicing receives. Which resulted in you accidently getting hit in the face my their stray ball. Tsukishima had snickered and that was the start of your current fight. 

"Ass"

"Bitch"

"LANGUAGE!" Daichi suddenly yelled out, causing Tsukishima to look over at his captain's direction. In that split second, you took it as an opportunity to snatch up a volleyball from the sidelines and like a professional pitcher, headshot that means ass, lanky, blondie. The sound of the impact was music to your ears.

A tick mark appeared on the blonde's forehead. "T-TSUKI!!" Yamaguchi frantically checked if he was alright. His incoherent worries seem to annoy the blonde further as he said "Shut up, Yamaguchi." 

He snapped his head towards you." What the hell was that for," he asked, irritated. 

" Oh, I thought you made that stupid face as a sign for me to throw shit at you, like those whack a mole games?" you said. You smiled at him innocently, which irked him even more. 

Poor Yamaguchi had both his hands up trying to calm his friend down. Your brother was just casually sipping water without a care in the world. Daichi came forward and asked, "Uhh, is she normally this aggressive?"

"Nope, she's the sweetest, goofiest and smartest person I know," he beamed.

He actually means it... the rest of the members thought, gaping at him.

"Do you carry that thing everywhere?" Kageyama appeared, pointing at the tablet in your arms and putting your feud with Tsukishima on pause. Hinata answered instead. " That's where she notes down all her research," he replied.

"Yes, my tablet is my treasure, containing all the analyses and observations I've ever noted. It was where I recorded down all the little things that make each individual unique. From their unconscious habits to their interest, their changes in expressions and body language. It is my proudest skillset!" you preached smiling widely, your hands on your hips.

You made eye contact with Tsukishima. You stuck out your tongue at him then turned away, resuming the fight between you both.

"Analyses my ass, you're just stalking at this point you creepy vermin," Tsukishima said, accepting and returning the provocation. "Vermin? Since you have the hots for me then what does that make you?" you said, smirking at him.

"Ooooooo," Suga, Noya and Tanaka collectively said, earning a sweat drop from Daichi.

" What nonsense are you spouting now?" he said massaging his temples. "Why the hell would I want to see your face more than I need to?" Tsukishima continued. He clicked his tongue. "Oh, I didn't peg you for a dine and dash then see you never kind of guy..." you smirked at him.

 "...Mr. 6.4 inches"  

Tsukishima gasped at you and leaped forward to cover your mouth. "What the fuck?!" he hissed into your ear. Hi face was completely red.

The team members were looking at you, then Tsukishima, wide eyed. Did they...?

Yamaguchi's soul left his body.  Tanaka was trying to reel it back. "Yamaguchi! STAY WITH ME!" he shook the limp boy. 

Your brother stood up then, eyes on the ground with tears falling from his face. Noya gripped his arm. "A-Are you okay? They probably didn't go all the way so don't worry," he said, trying to reassure your brother. Asahi just cried some more. Daichi had a rough idea what promise you made and broke but he sure as hell didn't know how to comfort your brother about that. "Y/n is a teenage girl after all, she's umm bound to? Do those... ahem... things," Suga said, patting Asahi's back.
