Love Equation [Tsukishima Kei x reader]

~short~

It was a regular Monday afternoon, the Karasuno volleyball team was getting ready for practice while you, Tsukishima's girlfriend, were doing homework on the benches.

"Well, that was easy." You mumbled, dropping your pencil on your open notebook. Closing your eyes, you closed your eyes and took deep breaths. You took the wonderful silence as a chance to finally rest up and take a small nap.

"Oi, give up already?" You heard a familiar voice and felt multiple jabs on your cheek.

You yawned as you groggily opens your eyes, rolling them at the sight of your smug boyfriend. "Actually, Kei, for your information, I'm-" You paused mid-sentence, remembering an equation you saw on the internet. You picked up your notebook and started scribbling the equation on it. "I've had a hard time with this one. Can you help me?" You handed the tall volleyball player the notebook.

He raised a brow as he looked at the equation. "Linear inequalities? This is 6th grade stuff." He smirked. "Are you that stupid?" Despite being his girlfriend, he never spared you from his rude remarks. But you were already used to it by now.

You pouted. "Well, I'm asking for your help, aren't I?" Turning your head, you spotted the other members. "If you don't want to, I'll call someone else then."

Tsukishima clicked his tongue and reached his arm out. "Just give me the damn pencil."

You laughed and handed him the writing utensil.

Tsukishima sat next to you and started solving the equation.

9x-7i > 3(3x-7u)
___________________
9x-7i > 9x-21u
-9x      -9x
___________________
   -7i > -21u
   -7i > -21u
   -7     -7
___________________
      i < 3u

Tsukishima looked up from the notebook to see you making heart signs with your hands. "I love you, Kei~"

Kei's face exploded to a red that can put Nekoma's uniform to shame. He shoved your notebook back into your hands, abruptly jumping up and walking to the team.

"I love you!" You announced from your seat on the bench. You snickered when you heard the reaction of his team and himself.

It's public affection like this that Tsukishima dislikes, exactly why it's the perfect revenge for being woken up.
