*** Prologue ***

"I had enough!"

Sawamura hung his head between shoulders, his fists clenched by the sides. The first year student has only enrolled in Seido High School for barely a week yet the amount of frustration he gathered was massive. He could not keep quiet with the things they were now. He had the every right to be mad about the baseball team.

As he stood in his school uniform at the back of the canteen, he was determined to voice out what he felt right then.

The one on the receiving end appeared patient, hands in his pockets, leaning idly against the wall. To be singled out here was nothing he imagined Sawamura would do to him. Sawamura was persistent to meet the senior alone for some reasons that he could not speak about in front of the other seniors.

With that the senior obliged and followed him here. There was no one else Sawamura could vent his anger to besides him. After all, it was basically because of this senior, Sawamura came to Seido High School. This very same person has what it takes to draw out his potential and make him a true ace.

But that dream was going to remain just like any other dream.

With the coach being too hard on Sawamura, he would not fulfill his dream of going to nationals. He understood that the coach was punishing him for his own good but ordering him to run for the entire week's practice was going to overboard.

Up until now, Sawamura had yet thrown a pitch ever since he came to Seido.

Akagi Junior High baseball team used to revolve around him. There was trust and teamwork. But everything was different in Seido baseball team.

None of his teammates acknowledged him. The coach judged him by his tardiness rather than his talent in pitching. Even the assistant coach who scouted him was disappointed.

Sawamura could not continue seeing himself going on like this. He could not afford wasting time running with tyres while someone else stood on the mound that was meant for him.

The title ace belonged to him and him alone.

If he could not see himself anywhere close to it, he would never attain it.

He deserved the training in his pitches. He deserved to find his true form. He deserved to be acknowledged by the team for his ace potential.

Sawamura needed all the help he can get.

He knew this senior would help him. Only he knew how good Sawamura was. After all, he was the catcher that Sawamura partnered with, for a strikeout on the fatso senior months ago.

"You have to help me!" Sawamura voiced again, frustration retained in his tone. "Talk to the coach and give me pitching practice! I have to get better or else, I can never be ace."

"Well," the boy with glasses smirked. "No one is actually expecting you to become one."

Sawamura winced and glared his amber eyes on his senior. "Are you serious?! That day, when you caught my pitches, you knew I had potential!"

"I would say the same thing to anyone Rei-chan scouted. She's pretty good in picking the good ones," the senior chuckled. "But it is really up to individual whether he can reach to his fullest potential."

"Aren't you listening to what I just said?! If I don't get trained for my pitches, I cannot reach my fullest potential! Just talk to the coach for me! He definitely considers if he hears it from you!" Sawamura persisted, his hands weighing in the air to accentuate his reasons.

"Why would I want to do that? I have better things to do. My advice is to be patient and do what the coach asks you to do. He knows you better than I do. More importantly," the senior turned away and started walking. "If you are going to continue ranting about this to me again, I don't feel like catching your pitches anymore."

"What?" Sawamura gaped in surprise.

A meek chuckle escaped the senior. "It's annoying whenever I cannot read your pitches. Your control sucks and it is hardly a fastball. If there is anyone who's going to be ace on this team, it is either Tanba or Kawakami. Understand, little junior?"

Chuckles became louder with every step he took, mocking and enraging the southpaw. The senior has always been mean to him from the start of the school term. The part where he tricked Sawamura to sneak into the lines on their first assembly was evident enough he could not be trusted. At times, Sawamura doubted if the catcher he met months ago was the same person walking away from him now.

His departing words really struck a nerve. Sawamura could not let him leave just like that. That senior had no idea that Sawamura has sacrificed his pride by begging him and he would not back down after being rejected bluntly.

A baseball clutched to his left hand. Sawamura rose his right leg and swung back his left arm.

"I'm not done talkiing, Miyuki Kazuya!"

In one toss, Sawamura shot his pitch forward. Miyuki barely turned back.

"Eat my best pitch, idiot senior!"

Miyuki reacted, eyes widened at the speed of the white sphere flying towards him. He thought twice between catching and shielding his glasses that could break upon impact. The pitch was easy to read but he was not sure he could catch it with half his body turned sideways.

The sound of impact was shortly heard and Miyuki hardly realised that his eyes were closed. It was probably out of fear as both his hands involuntarily protected his face in reflex. He slowly lowered his hands and peeked at his front.

A hand holding the baseball was seen a few inches from his face.

Miyuki held his breath too long that he could not release it just yet. He traced that hand to a female student standing closely next to him. Her coffee coloured hair flowed elegantly on her back, her fringes spiked like a princess tiara despite the cute hairband fastened on her head. She was shorter than Miyuki but her size was physically built like an athlete.

She took the ball into both hands and blew a heavy breath. "That was close."

Her soft voice nearly made Miyuki blush as he quickly calmed his breathing and adjusted himself. He wanted to see her face but a part of him intended to avoid.

Miyuki has never taken interest in girls. Baseball for life, is probably his motto.

This girl in front of him however was deviating him into a field he was very unfamiliar with.

Is this what boys supposed to feel when they are close to girls?

Heartbeat racing, lips turning numb, palms getting sweaty.

Like seriously?

A beautiful fit brunette with silky sweet voice under his nose.

How sinful.

His pride made a comeback, slapping himself with the fact that she saved him from getting rammed by Sawamura's fastball. He could at least be a man and offer her a thank you.

"Ano," Miyuki forced out a smile. "Thank you-"

"Sorry!"

The girl turned swiftly and bowed her head, her smooth hair almost shined when they fell hanging at the sides.

"Eh, what are you apologising for?" Miyuki batted his eyes.

"I... I know I shouldn't be here but I cannot help thinking something bad will happen so I followed you both here. For that, I'm sorry!"

Sweatdropped, Miyuki shook his hands. "Ah don't fret about it. And who are you again?"

"Ri-chan!" Sawamura yelped as he marched forward and pulled her away from Miyuki. "What are you doing?! Don't tell me you have been here all this time."

Without hesitation, she slammed the baseball on Sawamura's chest, stopping him to come closer. Her face was quickly revealed as she looked up, planting a fierce amber gaze on the pitcher.

Just as expected, big round eyes with long eyelashes. Her pink soft lips and chiselled jaw.

An angel has descended to Seido.

God isn't she adorable? Miyuki gaped.

"What makes you think pitching here will solve anything, Ei-chan?!" she yelled, her fingers squeezing on the hardness of the ball. "How many times I need to tell you, never let your anger control you? If you injure this mean senior, you will only downgrade yourself. You can get expelled."

"Ri-chan," Sawamura muttered defeatedly and looked down. "I... I know."

"Baka, you don't know anything when you're angry," the female student scowled, not letting a chance for Sawamura to recover.

"Why am I the mean senior here?" Miyuki interrupted and the beauty's amber eyes turned to him.

This is danger.

Like how angry Rei-chan was when Miyuki claimed himself having better eyesight than her.

Girls easily lose it.

After all, this unknown beauty was scolding the idiot and Miyuki thought it was macho of him to interrupt.

She looked straight at Miyuki.

Man up. Say something.

"Nice catch."

Sawamura flinched, "Is it really appropriate to say that now?!"

"What's appropriate is you apologise to me," Miyuki pretended to ignore her for a moment and he stabbed a glare at Sawamura. "Baka."

"Ah! Who are you calling Baka?!" Sawamura grabbed the ball and pointed at Miyuki. "Don't make me want to throw at you again."

"Don't think about it!" the girl pulled Sawamura away and bowed one last time at Miyuki. "Please excuse us! Sorry for the trouble."

"Ah, what a wasted time!" Sawamura burst and submitted to her dragging him away.

Miyuki creased his brows, watching their arms locked with one another. They both continued ranting at each other so closely that Miyuki felt his chest burned.

How come he was not informed that Sawamura has a girlfriend in school?

Kuramochi did mention about a childhood friend texting him from his hometown but never did he say there would be a girl in Seido uniform clinging on him like a heroine from a romantic movie.

Not forgetting to mention, her swift reaction to catch the ball was astonishing. Miyuki hardly realised her presence when he was talking to Sawamura. That could mean she was standing quite a distance from them.

For her to jump and catch that fastball, Miyuki was in the clouds for her.

Who was she? Why did she save him? Why did she go for such an extent for that pathetic loudmouth?

Miyuki could not stay quiet.

"Wait!"

Sawamura and the girl halted in their stride and turned to face Miyuki.

"Who are you, Miss?"

She blinked in surprise at the question but before she could speak, Sawamura wrapped an arm behind her neck and pulled her closely to his chest. Miyuki could have sworn he wanted to murder Sawamura for being too clingy with a girl in front of his senior. And it was not just any other girl.

The girl who possessed remarkable skills as a catcher, undeniably as good as Miyuki.

"Stay away from her!" Sawamura marred his face in anger. "She is out of bounds!"

Miyuki widened his smirk. "What do you mean?"

"She is my twin sister, Sawamura Erika!"

A beat of silence ensued as Miyuki could hear a pin drop. Deliberately Miyuki held the side of his glasses and squinted.

Twin sister?

Seriously?

Oi, stop pulling my leg, kid...

When Miyuki stared at their features since they are stood next to each other, he captured the resemblance.

"Eh?!"

Thank you for reading! Hope you enjoy!
