Chapter 1

"So this is Hakuou Academy.." Chizuru spoke to herself, looked at the big school buildings, where she'll be going to school from now on.

Yukimura Chizuru has graduated in Middle School and chosen to get Takugawa High School Girls'. However, it's because the school is a bit further from her house, she had no other choice but to refuse it. She also couldn't afford to buy a new house, and she especially didn't want to let her father lived alone. That's why she needs to refuse on choosing the Takugawa High School. She was hoping to get Shimabara High School Girls' where her two close friends, Sen and Kosuzu are.

Thinking about Sen and Kosuzu, she remembered her days with them. Most of it, she had a lot of sweet and precious memories with them. Thanks to them, she wasn't lonely in middle school anymore.

I wonder how they are now.. Chizuru couldn't helped but to smile. As she closed her brown eyes, her memories began to replay back of her middle school life once again...

In middle school, she has always been lonely. No, she wasn't a kind of unfriendly girl or something like that. Chizuru is more like.. has a timid personality. Whenever she tried to say something, she would ended up gaping like a fish, which confused her classmates a lot.

But she finally changed into different person thanks to her close friends, Sen and Kozusu.

"Ne, ne, you must be Chizuru, right? As in Yukimura Chizuru," a girl's voice spoke with a cheerful tone to Chizuru while they were having in recess. Chizuru was eating alone, as usual. But this young girl who is older than her suddenly being friendly to her.

"Um.. yes?," the young brunette girl answered, slightly confused/puzzled as to how this optimistic girl known of her name, although as much as she didn't meant to be rude, Chizuru hadn't met her before. She doesn't even know her name too.

The girl then smiled gently to her and sat next to her. "I never thought I could meet the Yukimura's daughter. You're really cute just as my parent told me," she said, put her chin on her palm of hands and couldn't helped herself to smile to the brunette girl. Meeting the Yukimura's daughter is like a dream to her.

The closer this optimistic girl is, the nervous Chizuru has become. That girl is the first one that has ever being so friendly to Chizuru. None of student, included her classmate would've come getting close to her, since every time the brunette mumbled, they would left her like an idiot.

There's something strange about that girl though...

"Um... have we met?" Chizuru finally asked a question that she's been wanting to know it. But hoped she didn't being rude to this cheerful girl.

"Oh, how rude of me," she covered her lips with her hand, and giggled for not introducing herself to the Yukimura. "My name is Suzuki Sen, from class 2B. But you can just call me Osen-chan."

"Oh... it's very nice to meet you, Osen-chan," Chizuru spoke to her in polite way. It is very out of character of her if she's being rude to a new friend. "How do you know my name?" the timid girl asked out of curiosity.

"I've known of Yukimura since my mom and your mother were quite close. My mom talked a lot about you. As to, how cute you are when you're still a baby, and she's also hoping to see you once you're grown up. I'm so happy to finally meet you, Chizuru-chan" Sen smiled once more, she wasn't just happy to meet the daughter of Yukimura, she was very glad to have a friend just like Chizuru. She noticed how lonely the brunette is for the first time she met. She thought that's just how she is in school. But as she kept watching to her all the time, Chizuru has a timid personality and couldn't able to say any word to her new friends, in which Sen would like to be her first friend.

"You know about my mother?" Chizuru questioned. As much as she can remembered, her parents died in car accident since she was still a child, and Kodou decided to adopt her. Despite he's one of her relatives, but Chizuru always called Kodou 'father' even though he's not her real father.

Sen nodded. "Yup. According from my mom, she's really lovely and beautiful too. She has a very kind and gentle aura, in which a lot of people love her. Especially your father, of course"

She didn't know a lot of her parents much. But hearing about them from Sen, she felt the need to know more about her parents. She didn't knew what does her parents were look like or what they would always do if they have been alive. It seems that Sen knows about Yukimura quite a lot.

"...Um, Osen-chan," the brunette girl called the cheerful girl's name.

"Hm? Yes?"

"Can you.. can you tell me more about my parents?"

Chizuru has been wanting to know more of her real parents. She was quite jealous seeing other kids went home together with their own family. And for Chizuru.. well, even if she had Kodou, she would like to walk home together with her real family as well. In fact, Kodou rarely went home too. So they hardly have some time to be together.

Sen nodded in taking as yes. "Of course. I would love to tell you of your parent, Chizuru-chan."

And later then, Chizuru and Sen became quite close. Despite Sen is older than the brunette, yet they were like best friends. They always eat together and playing together too. Chizuru has never thought having a friend like her.

"Chizuru-chan~! Over here!" Sen called out at the brunette girl, as school finally over.

When Chizuru approached.. to her friend, she met a young girl that has a same age as her.

"This is Suzuka Kosuzu, my adopted little sister. My parents took her in before she's in middle school" Sen introduced Chizuru to the bun-haired girl.

"I've heard a lot from my sister, Chizuru-chan. My name is Suzuki Kosuzu, I'm from class 1C. We hope we can be friends too." Kosuzu said gently, and smiled who had a same kind smiled as her foster sister.

"Oh... of.. of course, we can, Kosuzu-san" Chizuru said nervously, managed to have a new friend with a same age this time.

"Well then, we should go home together. You can come with us too, Chizuru-chan." Sen said, ready to return home.

"Um.. are you sure about this? My house is a bit further though.."

"Don't worry, don't worry. It's not that your house could take us until midnight, right?" the cheerful girl giggled, making Kosuzu laughed as well, though Chizuru could only gave an awkward laughed. ..

Days went by, they began quite closer and closer. And Chizuru has changed lately. She wasn't the timid that Sen and the other students once knew. The brunette girl has become friendly and talked confidently with everyone. It wasn't a bad thing though. Sen was happy to see Chizuru changed into a better one. ..

Time passed so quickly, Chizuru couldn't helped but she could felt herself a little lonely. Sen is almost graduating, and she has chosen to get Shimabara High School Girls'. How she wished Chizuru has a same age as Sen so that they could go to school together. But she knew there's no other choice but to accept their fate. In fact, she still had Kosuzu, so she still doesn't seem to be lonely yet. Even after Sen has graduating, the three of them promised to each other that they will be having a best friend dating(that's what Sen called it) in every weekend. And they always did it in every weekend, in which it made Chizuru happy.

But after Chizuru has graduated in middle school, she would be lonely once again, since Kosuzu has chosen to get Shimabara High School Girls' just as Sen got. It was really very unfortunate for her to get Hakuou Academy, instead of getting Shimabara High School Girls'. According from Sen, Shimabara High School Girls' are only for students from rich family. The Suzuki clan is one of the richest family and also known of tea ceremony school.

As for the Yukimura clan, they're no longer one of richest family anymore since Chizuru's parents died. In fact, the brunette girl didn't know what does the tea ceremony school is like, that's why the Shimabara High School Girls' refused to choose her. However, even if she couldn't able to get the Shimabara, Sen and Kosuzu always tried to cheer her to be a little optimistic even if they can't be together just like they had in middle school.

I won't let you down, Osen-chan.. Kosuzu-san, Chizuru thought, tried to think positive rather than negative. It would be bad if she's being pessimistic, especially for the first day in Hakuou Academy.

"..."

But little did she knows that, when she's taking an enrollment of Hakuou Academy, she discovered that it's an all-boys high school?! Chizuru didn't know that the Hakuou Academy is truly for high school boys. How did she got the enrollment, you might ask? It's all thanks to Doctor Matsumoto who got the enroll of Hakuou Academy from his friend, who is the principal of Hakuou Academy, Isami Kondou.

Matsumoto is also Kodou's friend, they've been known each other since they were in university. Chizuru also known Matsumoto since he visited her house sometimes in whenever Chizuru/Kodou sick. He is very kind and often worried about Kodou since her foster father always kept working all days, including holidays too! Other than that, Matsumoto really does cared about Chizuru and Kodou ever since the brunette's parents died. It was very unfortunate for Chizuru, to have lost her parent since she's young.

She, especially getting separated with Kaoru, her twin older brother. Chizuru didn't know much about Kaoru, but from what she had learnt from Kodou, Kaoru has a great resemblance with Chizuru, though he had a short hair instead of long. He's been taken by Nagumo clan, so she doesn't see or meet Kaoru a lot.

But Matsumoto really happy when Chizuru accepted on taking an enrollment of Hakuou Academy since Kaoru would be in that high school as well. She might be a little lonely, yes, but since Kaoru would be there, the brunette would no longer be as lonely as she was in middle school. Though, he hoped her twin older brother wouldn't mind if she went to the same high school as him.

"What is this, Doctor Matsumoto?" Chizuru asked, after Matsumoto gave her a registration paper. Matsumoto visited her house once again though he didn't came here to give check up on Kodou or the brunette girl. After he heard she refused on taking the Takugawa High School, he decided to let Chizuru applied on an interesting high school.

"It's Hakuou Academy. I've heard that you've refused on getting to Takugawa High School. So, you might as well taking an enrollment of Hakuou Academy." Matsumoto answered.

"But.. where did you get this enrollment?," she asked another question that's been wanting to know. She had never heard of Hakuou Academy before, especially, of all the people that Matsumoto knew, why Chizuru?

"Oh, a friend of mine, Isami Kondou, a principal of Hakuou Academy gave me that. Though I do not have daughter nor son. So you should applies on that school."

"But.." Chizuru began to protest. "I can't take this school. You should give this to someone else." She couldn't accept this offer. What if, this high school is better than Shimabara High School Girls'? What if, she get more fun than Sen and Kosuzu? She didn't want to betray her close friends...

Matsumoto then gave a dissatisfied expression on his face. "Even so, where would you go to school, then? Don't tell me you didn't want to continue on studying."

It made sense. Where would she's going if she refused Hakuou Academy? She didn't want to let everyone down, especially Kodou, Sen, Kosuzu, and Matsumoto too. If she does refused another high school, where would she study then? She never thought this could be difficult than she ever had in middle school.

So in the end, Chizuru accepted Matsumoto's offer and taking an enrollment of Hakuou Academy. It wasn't her first day in school yet, the brunette girl went to Hakuou Academy for taking some stationary, uniforms, and others stuff from school.

But this shocked her the most

"Congratulations on getting Hakuou Academy."

"Oh.. Thank you," Chizuru said, bend her body politely.

"We hope to see you in the first day at school. Here's the timetable, oh and by the way, you should cut your hair too since it's against the rules."

"What..? Does keeping a long hair really against the rule?" Chizuru said, surprised as she heard about this strict rules.

"Of course. Boys can't keep hair longer. It would be too weird for letting boys keep hair longer." he laughed.

...Eh?

"This is, after all, a high school for boys. There isn't any student girls. Not even a worker nor teachers."

"Wait.. you mean, there isn't truly have a student girl in this school?" Chizuru questioned. It was surprised her that she's the only a female that went to the Hakuou Academy. Does this person didn't noticed that she's a girl..?

"Well, I did say that. Though, Kondou-sensei was planning to make this school for both, high school boys and girls. Unfortunately, there's isn't any female students for 2 years, so he decided to make this school for boys."

No.. no way.

"Anyway, have fun in Hakuou Academy. Don't be a bad boy, though."

As the worker left her, Chizuru couldn't helped but she could felt herself paralyzed. She couldn't able to move nor think anymore.

Right now, she's been applied an all-boys high school. She won't met some friendly and kind high school girls. Only rude and aggressive high school boys. The more she thinks about of her new high school life, the more she became to scare of what life she'll get if she studied there. What would happened then? If she pretends herself to be a boy, will they noticed of her? If they finds out of her identity, what would they do to her after that?

She never thought she could fell into Hell so early...

But in the end, she decided to go to Hakuou Academy and changed her image to keep her from knowing of her real identity. She didn't cut her hair yet, but she uses a wig of short black hair, and of course, she wouldn't wears a make-up. But when she took a closer look at the mirror, her face does had a little boy-ish. No wonder the worker thought she was a boy. Though she's glad that she get accepted on getting Hakuou Academy. If he does thinks her a girl, she would've rejected on getting that high school already.

She took a deep breathed and ready to go Hakuou Academy. Her new high school life. She didn't mind if she has no friend in school. As long as they didn't find out of her real identity, then she didn't mind.

Hakuou Academy.. will be my new high school life.

A/N: There you go guys. Hope you like it. Some of it I followed up to the original SSL though some of it are not. By the way, I think I should give a little information about this fanfic. Kazama, Amagiri, Shiranui, Okita, Saitou, and Yamazaki are in second year. I didn't want to make them third year because... there's something I need to add in the future chapters.

I also write OOC-ness just in case if I did make them OOC.
