Forbidden Love (Kageyama x Reader)

Forbidden Love one shot

~Flashback~

One early morning, Oikawa Tooru was walking towards the gymnasium of Kitagawa Daiichi. He stopped outside of the door to hear his little sister (Y/n), who was a first-year, talking to someone....alone. And that someone was a boy. Oikawa peeked inside, and his face hardened in anger. The boy talking to his little sister was Kageyama Tobio. Oikawa flattened himself on the wall listening to their conversation.

"Tobio, I wish we can show everyone how much I love you," Oikawa heard his little sister say to the boy.

He heard Kageyama sigh, "You don't know how much I want to do that too, (Y/n)...but your brother-"

"I'm so sorry, Tobio."

"It's not your fault, (Y/n)."

"I love you."

"I love you too."

Oikawa's teeth gritted, and his fist tightened.

'I don't accept this! Tobio-chan is only using her for popularity and doesn't love my baby sister. He's stealing her away from me! (Y/n)-chan is mine, and only mine!"

Oikawa thought for a few seconds when an idea popped into his mind. He smirked and quietly left.

•At Lunch Break•

Oikawa was walking to (Y/n) 's classroom to give his sister her bento when he noticed many students gathered around there. He stood behind quietly and saw his sister and Kageyama yelling at each other.

"Just because we can't announce our relationship in public doesn't mean you have to cheat on me behind my back!"

"I never cheated on you in the first place!"

"Don't make me laugh, Kageyama! I'm very thankful for this person to show me proof of you cheating on me!"

She held up three photos of Kageyama and a girl. One was holding hands in the mall, laughing. The second was the male hugging the girl from behind on a bench in a zoo. The third was of the two kissing in the gymnasium of Kitagawa Daiichi.

"Are you kidding me, (Y/n)?! Do you think I would do that to you? I love you!"

"You love me, my butt! Who is she, Kageyama?!"

"It's photoshopped, (Y/n)! I swear I don't even know who that girl is!"

"I can't believe you used me after everything we did together! I gave you so much love, and you did this to me in return?! Just because I'm popular doesn't mean you can use me as you please!"

(Y/n) started to walk away until Tobio spoke.

"You know, your dream is childish. Becoming an artist? What a joke! Your singing is like nails on a chalkboard, and your dancing is horrible that any child is a better dancer than you. And you can't rap at all! You think you're good at everything, but you're not. You'll never be a successful artist."

The girl turned to him with teary eyes, glaring at him.

"I HATE YOU, KAGEYAMA TOBIO!"

Kageyama's eyes widened and shook, tears started to spill. (Y/n) ran out of her classroom, making the students make way for her. She accidentally bumped into a tall figure and apologized. She looked up to see her older brother and immediately hugged him tightly.

"I'm sorry, onii-chan," The girl cried on his chest while Oikawa wrapped his arms around her protectively and ran his hand up and down her back.

"It's okay, (Y/n)-chan," Oikawa told his sister, holding in his excitement.
