"Nice block Tsukki!" she cheered.

"Tsukki nice kill!

"Don't mind Tsukki!"

It's Karasuno's male volleyball team versus Nekoma's. It is just a practice match but she cheered the team as if it is a tournament.

She watched her team and also the opponent to gain data and information in their gameplays as their manager.

She stared beautifully at the Karasuno's number 11. She watched his wide arms blocking the ball of the Nekomas. She watched his long legs as he jump high spiking the ball.

Ahh, how beautiful-she thought. She just have an obsession looking on some masculine built bodies.

(at home)

"Hey, Onii-chan what's wrong?" She asked the Karasuno's setter and also her twin brother, Kageyama as he grinned his teeth and staring at his dinner.

Their parents were on their vacation trip and they were left alone. So it seems quieter than usual.

"Tch. Nothing." he answered still looking angry.

She finished her dinner and rushed into the living room to watch her favorite TV show.

"You're gonna wash the dishes, Onii-chan." she said happily and turned on the TV as she lay on the couch lazily.

After he finished washing the dishes, Kageyama stood in front of his little sister covering the TV show she is watching.

"Hey Onii-chan I can't see the TV!" she said as she raise the upper part of her body on the couch to see the TV show.

Kageyama's little sister looked at him but she saw him glaring at her.

"W-What? Are you mad?" she asked.

"Hmph. You only cheered that four-eyed freak earlier. Is he your boyfriend?" he asked possessively. Having a thought of not giving his precious little sister to that bastard.

She was surprised after hearing his question.

"B-B-B-Boyfriend?! Kei-kun my boyfriend? No way!" She answered. She felt grossed after imagining him become her boyfriend.

"Then why are you not cheering on me? I have plenty of good tosses!" He yelled.

"Why do I have to cheer you? Baka." She teased.

He grinned his teeth and threw death glares at his imouto.

She chuckled when she saw his reaction. Seeing him get pissed off makes her satisfied.

He climbed on top of his little sister making her lean on the side of the couch.

"H-Hey! What are you doing baka onii-chan?!" She said.

"Punishing my little sister." He said with his big freaky smile on.

"W-What?! Noooo!" She shouted and pushed his shoulders. But his broad shoulders are too strong to push her into the couch.

Kageyama chuckled with an evil grin. His imouto felt scared just seeing his evil grin like those villains in the TV shows that she watched. They were always like this and she's the only one that Kageyama can show this side of him.

Still not ready being punished, her devilish brother suddenly bit her neck that make her scream.

"Ouuuuch! Get off of me! S-Stop it!" she yelled and punched his shoulders weakly because of his teeth still buried on her skin.

"O-Onii-chan! S-Stop it! It hurts!" she continued.

He also bit her arms, legs and the side of her stomach making her feel more pain.

He then let go of his imouto and glared at her. "If it didn't hurt, then it's not a punishment, dumbass imouto." He said.

His little sister covered her neck where he bit her still feeling the pain. Her eyes closed and eyebrows formed. Kageyama saw his precious imouto in pain and looked away.

"I-It's your fault for not cheering on me earlier." He said in a low tone feeling sorry for biting her. But because of his pride, he don't want to tell it.

"It still hurts!" She said and tears are about to form into her eyes. "I-I'm going to sleep!"

She stood up and stormed towards her room. After entering, she slammed the door and lay down on herr bed.

Kageyama tch-ed with his hands under his lap, still sitting on the couch. He then finally gained courage to apologize to his twin little sister so he stood up and walked towards her room.

"I-I'm coming in." he said.

He closed the door after entering and saw his imouto laying down in pain.

She looked at him standing in front of her bed.

"What? Still not satisfied?" She cried in anger and got up.

"I'm just here to say s-so..s-sof..s-sorr-"

"Get out of my room baka onii-chan!" She yelled and threw a pillow on his face but he catched it easily and made her feel more mad at him.

He sat beside his imouto and hugged her tightly feeling sorry for what he had done.

"H-Hey! L-Let go!" She protested.

He let go of her and looked away blushing.

"I-I don't want my imouto to have her attention to others. E-Especially to that four-eyes." He explained still looking away.

His little sister finally calmed down after hearing what her precious brother told her.

She laughed a little and Kageyama looked at her confused but happy now that you're laughing.

"So, my onii-chan only wants my attention to him?" She smiled and put her face closer to Kageyama's face which made him blush.

"Y-Yeah." He answered feeling a bit shy.

She smiled seeing her onii-chan blush. She suddenly have an idea.

"Well then you're going to sleep here beside me. My neck stil hurts you know. Baka onii-chan." She said.

"W-What?! But your bed is only for one person!" He protested.

"We'll fit. I'm sexy you know." She chuckled.

He sighed and lay down on her bed tiredly closing his eyes to have a rest.

"H-Hey! You're too fat!" She teased. "I don't have enough space!"

"Oh? But you said your sexy." He said still eyes closed.

"Sexy not skinny!" She yelled still sitting on the side of her bed.

He suddenly pulled his imouto's waist that makes her lean against his bare chest. She almost feel his heartbeat.

"Your too light. Are you eating properly?" He asked her. "Well, I don't mind. Let's sleep now. I'm tired."

She smiled and nodded.

"I love you, onii-chan." She whispered.
Kageyama hugged her and turned left to make both of them fit on her single bed. They're now facing each other very close.

Instead of saying 'I love you too, imouto', which is not like him, he kissed her lips and smiled which is very rare for him to smile.

He then puts his hand on her waist as both of them fell in deep sleep.
