From Boy to Girl

First Part

The air was cold and the grass felt damp. The moon was almost gone and Hinata Shouyou was still asleep on his bed. His alarm suddenly went off, making him stir on his bed. Tossing and turning around, the orange haired boy stood up from his bed and change to his uniform. With a yawn, he left his house bidding a kiss to his Mother who saw him off.

Taking his bicycle out from the garage, Hinata sat at the small seat. Placing his foot at the top of the pedal, as soon as he started to move it around. Passing by mountains and long roads, Hinata had finally arrive at his school.

Parking his bicycle to their schools parking area. Hinata locked it with his bicycle key. Stretching his muscles with a yawn, the lad made his way to their club's locker room. Planning to prepare for another morning practice with his club members.

Walking towards the club room, a gust of wind had then passed him by. Opening his eyes widely to find his raven haired crush who he considered as his rival running in a haste.

"As if I will lose to you" the lad thought to himself, as he started to run. Moving his arms and feet, a sudden feel of heaviness and pain erupted from his chest. "It hurts." he added in a whisper to himself. Not realizing what it is, the lad just rubbed them off with his hands and continued running.

The two were now below the building, huffing and trying to catch their breath. Stepping his foot on the stairs, his crush made two steps ahead of him, planning to have another race to reach the locker room. With Kageyama's victory for arriving first inside and got to change ahead of him. The lad left the orange male with a smirk from his face.

Placing his bag on the shelve with a pout, Hinata had then took off his coat. Unbuttoning his Gakuran with his hands, he took it off together with his hooded shirt. Feeling weird around his chest area, he examined it with his eyes and hands. "Feels round and squishy. Feels like a female breast" are his first thoughts upon feeling his now rounded chest.

Realization had then hit him as he took of his pants and shorts, to find his elephant gone and replaced with what looks like a flat mound.

"IT'S GONE!" he shouted in silence, feeling his dignity as a male gone and was turned into a female. Trying to calm himself down, a knock from the door had suddenly entered his ears, making him flinch.

"Hinata? Are you ready? Morning practice will start soon" Kageyama Tobio had called out to him, turning the knob with a twist. Hinata had his head sweat as he tried to change as fast as he can.

Putting his legs in the holes of his shorts, attempting to cover his female body. But failed as the black haired lad, had already opened the door wide with his eyes wide. With his face and body blushing red from seeing a woman butt naked inside, kageyama had then closed the door.

The man remained stilled like a statue at the door and waited for the girl to scream, but heard nothing. It was then he remembered, their room was only for them to use. Means, only men can use the room.

"Why is there a girl inside?" kageyama had then thought, opening the door with a loud bang.

Standing in front of Hinata's bag, digging her arms inside. The man was shocked to find a woman butt naked and was now then stealing from one of his friends. In a hurry the man had locked the door and grabbed her arms, asking what she was doing.

Hinata was startled after being pushed to the wall, facing her crush's face closer to hers. But her blood drained from her body, after looking at his piercing glare to her face.

"What are you doing here? And Who are you?" Were his demand for her to answer. Holding both of her wrist to the wall.

Hinata tried to pry her hands away from him, struggling with all her might, trying to kick him. But failed, as the man was stronger than she is, even before she turned into a woman.

"Let me go, Idiot kageyama" the orange haired lass shouted with her feminine voice. Trying to pull her hands down from the man.

"Answer me first, Who are you and what are you doing with Hinata's bag? And Why do you know me?"

"Let me go! It's me Hinata" the lass cried from the pain from her wrist.

Not believing her words, Kageyama had then tighten his grasp to her. "Don't tell an obvious lie. Hinata is a man and I am sorry but I say your naked body in front of my eyes." The man ended with a huff, still holding her wrist with his hands.

"That's why I am telling you. I am Hinata, Hinata Shouyou."

"LIES"

"ARE NOT, So let me go!" releasing a loud breath, Hinata faced the man with her tear filled eyes. The man had then recognize the resemblance with the male Hinata to the Hinata he is now holding. His eyes had then widen from seeing her teary eyes, the man instantly let got of her wrist. Letting the lass to rub the pain off.

"You do look like Hinata. Perhaps his younger sister? He did told me that he has a younger sister."

"No, I am not his younger sister. I am Hinata Shouyou, who you defeated two years ago during middle school and has been persisting you to play toss with me since first year high. I AM HIM, Believe me Idiotic King"

The man didn't want to believe, but her annoying tone of voice, the way she speaks and move her body. Are exactly how his orange haired friend acts towards him. "If you really are him. Tell me one of my secrets that I told him and the one that he told me."

"Fine, come closer. I don't want anyone to listen or overhear us" The lass raised on her eyebrows with a annoyed sigh, pulling his ear to her mouth level. Whispering the secrets that they had shared by accident.

"When you were turning five years old. Your mother had you dressed up like girl during your fifth birthday for the whole day. I knew that, because I accidentally saw the picture that you hid together with your books at the lowest bookshelf inside your room."

The man immediately felt his checks redden, thinking Hinata had told someone the secret that he had threaten him to keep his mouth shut. Planning for his revenge, but the lass was not yet done and continued to whisper to his ears with her face flushing red from embarrassment.

"Before we graduated from First year. I confessed to you, after I had asked you out to play volleyball with me at the town's gym."

Kageyama had then remained silent. Knowing that there's no way Hinata is willing to share his secret to anyone. Not even to one of his closes classmates or friends.

"If, that is not enough. I tried to kiss you wh-" were the words that had left her throat as the raven haired man had then muffled her mouth with his hands.

"Okay, I get it. You are him. But why are you a girl? I am sure you were a man."

"I don't really know. I just found it out when I was changing and then you came knocking at the door."

"I see" there was a pregnant pause between them before voices from the outside had called their attention. Turning their heads together. The man had then told her to dress properly.

Hinata was already done changing. But the bust on her chest failed to stay hidden as it was slightly bigger than it was before. To add there problems, Hinata's nipple was clear on his view, which made him feel blood rise to his head. Taking his jacket off, the man had thrown it at her front. Telling her to wear his jacket.

The door was already opened and in came the older members of their club.

"What are you guys doing?" Their Ryuusuke Tanaka asked curiously to the couple, standing besides each other as if they are waiting for them to come.

Hinata and Kageyama spared a glance at each other and replied with a shook from their heads. The older student raised one of his eyebrows and informed them to hurry so as to avoid being scolded by their captain. In a hurry the two second years had left.

Before they had left the room, Tanaka had then noticed something weird with one of his underclassmen. He was about to ask, but the two had already left.

"You're late" came the voice from their new captain.

The two bowed their heads to apologize, but was only ordered to have their punishment after class hours.

Their morning practice had already ended and Kageyama felt like nothing had change, except when she runs a bit slower than she used too. After finding out the Hinata turned into a woman, his eyes has been stuck with her. Observing her every action, and trying to keep her away from being asked about her condition.

Classes had already started, and it was lucky for them to be in the same class and a seat across from her. Allowing him to set his eyes on her back.

On her side, the lass has been noticing his constant glare towards her. Making her feel uncomfortable and unable to focus on her class. She tried as much as possible to avoid his gaze, but failed as the man have been following her every move. Her heart would beat when she saw him stare at her, but all she thought was a loving gaze was a piercing glare instead.

It was already lunch time, when Kageyama had sat beside her at the rooftop to eat their lunch.

"You're weird" the orange haired lass who was wearing her usual uniform blurted towards her crush.

"That should be my line, Dumb-ass" he replied back, eating from his lunch box while munching on his food.

"Don't call me that, and you're really weird today"

"How so?"

The lass opened her mouth to speak with her brows furrowed, "Because you've been glaring at me. What did I do to you?"

"Nothing. Jut observing that you really are not lying"

"Oh really? So what I just told you this morning is not enough? Fine then. When you were-" came her muffling voice, being covered by his hands again.

"I believe you already. Just stop that"

"Then why is it that you have been glaring behind my back? And following me around?"

He was about to speak, when suddenly someone had intervened with their chat.

A blond haired lass, had then came. Telling Hinata that their homeroom teacher was looking for him. With a sigh the orange haired lass, made her way towards the door. Leaving Kageyama and Yachi alone.

The lass was curious and asked if something happened, but the man only responded with a 'No'.

Classes for the day had already ended and Kageyama had still continued on following her around. Hinata had then turned and warned him not to follow her with her face flushing red. But the lad only ignored her warning.

Upon arriving closer to their club room, the lad had then warned her. "The club room will be filled with males, and it will be harder for you to change. So change later when they are out. Got it?" Nodding her head in response, the two continued on their way to the club room.

"Before you change, wait for the others to leave" Kageyama had warned to her again in a whisper, still following her from her behind. Arriving the club room with a loud greeting. The members had their laugh stifled, making fun at how she sounded like a girl. Hinata only pouted and joined their chat, placing her bag to the shelf and waited for the others to get dressed.

Nishinoya was curious why she was not yet changing her clothes, with a smirk the lad pried for her clothes. Trying to take it off from her body. But a glare and a harsh hold from his wrist by a raven haired man wearing a scowl, halted his fun.

"What is it Kageyama? That hurts" their small upperclassmen complained. Trying to remove his hands from his wrist. Chikara had then came and asked them to hurry to the club room, while scolding the taller man to let go of the wrist he was holding.

Realizing what he was doing, the man let him go and apologized. Yuu only raised one of his eyebrows and smiled, telling him it is not his fault. "I should be the one saying that. Sorry about that Shouyou, but we're both guys. So there's really nothing to be ashamed off"

"No it's okay, my stomach just kind a bit hurts."

The captain had heard her reason and asked if he want to rest. But Hinata didn't agreed and decided to come later, after she was done changing her clothes.

The two were finally left alone. Making her way towards her bag, she opened it and took her school jersey out. She was about to take her clothes off, when a cough from the man inside the room caught her attention.

"You shouldn't take off your clothes, while I am here"

Hinata nodded her head and organized her clothing, while waiting for him to finish changing. Kageyama was finally done and was now guarding the door outside, helping his troubled friend to change without someone knocking on their door.

Changing back to her gym clothes with her jacket zipped closed tightly to her neck, making sure her breast is not obvious to their eyes. Opening the door slightly to find the raven haired man standing with his back facing her. Tapping on his back, telling him she was done.

Arriving at the gym, the students had already started with their practice. Jumping and practiced diving to the ground. Hinata had then started to join the group.

"Are you wearing your jacket during practice?" Yachi had asked curiously to her, tilting her head to the side with a smile. Smiling towards the orange haired male who was stretching his body.

Hinata only nodded her head in response and made her way to the lining students. Calling for a toss, Hinata made a long jump and hit the ball with her open palm. With a loud thud, the bouncing ball hit the ground. Turning around to allow the others to jump.

A call from their Coach had then caught their attention. Telling the students their next course, the coach had then left as he had another plans for the day.

"I bet you are going out on a date with Ms. Takeda" the bald player teased, followed by the smallest member of their club.

"Now that you mention it, Ms. Takeda was in a hurry when she left." a short spiky haired wing spiker had called, making the teasing students to widen their grin. With his face flushed red, their coach had then left, trying to ignore the wolf whistle he was given.

"Not bad Coach Ukai. Do your best and Grab the chick" Takeda added, followed by another cheer from the Libero.

The upperclassmen were having fun with practicing and jumping with the first years, when one tall fresh man had accidentally hit the ball towards Tsukishima's head.

"Tsukki, Did you brought the CD, that I asked?" a freckled nose lad had asked to his blond haired friend. Standing in front of him, when a ball had then made a thud to his head. Tadashi was two feet away, for him to save his dear friend. In the end it end up with him bumping unto Hinata with his tall and heavy body.

Hinata and Kageyama were alone, practicing her receive with his toss. Hinata would sometimes miss hitting the ball, as the man's gaze in front of her made her lose focus.

"Give me a Toss" the orange haired lass called to him, trying to hide her embarrassment.

The man had immediately threw the ball to the air, positioning his hands and hit the ball when it came closer to his arm's reach. Hinata had gather her hands together, trying to reach the ball. She turned around, but a body weight had hit her instead.

Hinata was lying on her back, with another warm body on top of her. Trying to stand, but a squish from her chest made her widen her eyes and halted her to move. The players had then gathered around the two, worried for the smaller lad. The first year shortly apologized to their tallest player and to the orange haired lass.

The black haired man had then noticed how the lass was stilled and silent from the ground. Noticing the hands on her breast, he directly placed his hands to Tsukishima's arm, removing the lass under his bigger body.

"Sorry about that Chibi, you're too small that I didn't saw you" he made it sound like a tease, but the male didn't mean to bump into her. Staring at his hand, trying to understand what he felt when he accidentally grabbed his chest, "Soft?" were the thought that entered his mind. Ignoring the noisy loud pitched voice beside him.

Pissed, the woman had then started to bicker with the taller man, and it only got louder when Tadashi had join her one sided squabble.

Kageyama had then dragged her away from the group, making his way out to drink some water. The orange haired lass was shouting from his tight grip, ordering him to let go. Her hands was finally free, when Kageyama made sure no one is near.

"Are you alright?" the lad had asked worriedly towards her, after witnessing that her breast was being groped by someone.

"What are you talking about? Of course I am fine"

"Not that, Tsukishima touched your breast, didn't he?"

With a blush, Hinata placed her palm behind her head, trying to get her way out from the uncomfortable conversation. "Oh that, well that was."

Kageyama only raised one of his eyebrow with an irritated scowl on his face, waiting for her to answer. "Answer me Hinata."

With a huff, the lass answered to his demand. Starting to get pissed with his constant staring and nagging "Seriously, what are you so concerned about? You were not like this when I asked you to be my lover, you even ignored me for almost a week and I tried my best to forget. It was just a slight touch to my chest. Further more I am a guy. A GUY. Didn't you told me that? or could it be you started to fell in love with me, after I had turned into a woman."

"That's not it Airhead."

"Then what?"

Uncertain on what to speak, the man remained silent.

The orange haired lass, composed her self and breath her air thought her noise. "Seriously Kageyama. You don't have to take care of me. Well thank you for saving me back there. But I can do it myself. Furthermore, I don't want you to fall in love with me like this."

With her parting words, the lass had left him alone.

Club activities were already done. Except for the two players who got late this morning. The captain had asked them to clean the balls, as their punishment for being late.

The two remained silent as they scrub the balls clean from dirt. Hinata would spare a glance towards him in a minute, then back to her work.

The last ball was already squeaky clean, when Hinata stood up from where she sat, placing the ball to the big cart. Kageyama had then placed his palms to the handle and started to push them towards the storage area. With a knock from their captain. The two had left in silence without talking to each other.

The others were already done and had already left. Grabbing her bag from the shelve and waited for the others to finish. The last player had already left, when Hinata had finally decided to change. Not noticing another presence inside the room.

Planning to change her uniform, the lass halted when she finally saw the man sitting behind her.

"Sorry" The man had breathed, grabbing his bag and placing it to his shoulders. "I'll try not to bother you anymore." With a soft thud, the male had left the room.

Her tears started to gather to her eyes, his words ringing to her ears. "I'll try not to bother you anymore." She did told him that she can do it alone. But being told by her crush with those words, her heart felt a squishing pain.

With a laugh the lass had then mumbled to her self "I reap what I sow. Damn that hurts coming from his mouth". Crouching to the ground, she closed her eyes with her hands.

Passing by the school gate, Kageyama felt his heart in pain after leaving those words he didn't mean to tell her. "I am sorry, I was just worried about you" were the words that he had planned to tell her. But after seeing her scowling face, it made him tell her those words instead.

Hitting a tree that he had passed by, making the passer by surprised with his violence. "I am such an Idiot. A big Idiot" he thought to himself as he slid down with his forehead pressed on the tree. Regretting the words that he had told her.
