I said I would update this story once per two weeks but… Forget it! The more reviews I got, the faster I update XD I prioritize story that gets more reviews, since my other story (sadly) hasn't gotten any review till now I decided to update this fic first.

Thanks for reading this story till this far. It's seventh chapter already :D

Disclaimer: I do not own either Tenipuri or its characters. The OCs, plots and characters developments belong to me though.

Sorry for bad English and typo.

Ch7: Private Tutor

Ever since the day Tsubaki had made Zaizen escort Tsubasa home, her brother kept whining. It seemed that something had happened between the two boys. She was really curious about it. She wanted to know about it, but she couldn't. Every time she tried to ask him, he always made a face from only hearing her mentioned Zaizen's name.

Tsubaki leaned her cheek on her palm and sighed. Maybe putting those two together wasn't a good idea. At first she had thought they could be good friends, as Zaizen was the only one who knew that Tsubasa's true identity. She had thought it would have been nice if Tsubasa had a friend that saw him as a boy.

Continuously tapping her pen onto one of the tables in library, she gazed on a math book before her. Her teacher, Yamada-sensei, had given her extra homework during the previous supplementary class. If she didn't finish it correctly, she would have to attend another supplementary class in the future. It would be really troublesome. She would not only lose her free time, but also have to miss her club activity. Sanae would be angry if she didn't show up in kendo practice again, no matter what excuse she used.

It couldn't be help. The only way to avoid the supplementary class was by studying more diligently and finishing her piling homework.

Right now, she was diligently using her lunch break to finish some of the homework in the library. She frowned looking at another difficult problem she couldn't understand. Geez, she really wished she could enjoy her lunch break like her friends outside instead of having a sort of date with math books in a place where people rarely visited to.

She was really absorbed in her thought that she didn't realize someone else was also in the library. She finally noticed his present when he approached her and stood right next to her.

"Zaizen-kun! What are you doing here?" She asked in surprise. Of course she wouldn't have been that surprised if she had known that Zaizen had been there from the beginning. Note that this was her second time failing to notice that he was around…

"I'm part of the library committee." He explained shortly.

Her mouth formed an 'o' shape. She had thought he had been a type of person who didn't bother to join any committee (just like herself). Then again, she found that library committee suited him better than any other committee like the broadcasting or health care ones. Anyway, that was the end of their conversation. She didn't know what to say so she tried to concentrate on her homework again, or at least, she tried to pretend concentrating on it. It was quite hard to think clearly when she had his stare drilling through her head.

He watched her looked back at her book and frowned. Were third year's subjects that hard? He had never thought about it since his seniors looked like they had no problem with school. To think again, even he hated to admit it, most of them were sort of brilliant students e.g. Shiraishi, Kenya, and (uh) Koharu.

Out of boredom, he took one of her books on the table which happened to be her English book. She noticed it and looked up at him. She bit her lower lips as she saw he frowned reading the book.

"This is horrible," He commented. "The grammar, vocabulary, even preposition… You basically mess up with everything."

"No one ask your opinion." She snatched her book back. Indeed, English was one of her worst subjects, but she didn't need a second grader's comment. "Don't talk as if you understand about it. You haven't even learned about it yet."

"Well, about that…" He crossed his arms and started explaining. His explanation was very long and detailed. She could only look at him in awe as if he had been a living English dictionary. Her head had gone blank when he finished with a cocky 'how's that' smirk.

"Aaa… Zaizen-kun," She said after recovering from shock and regaining her voice back. "What about substituting me in the upcoming test?"

"I refuse."

"I'll make you a bento again."

"That'll cost more than bento portion for a whole year."

"Then, what about shiratama zenzai?"

"No need."

"Che, Zaizen-kun you stingy!"

"I guess I am… Anyway, have fun with the supplementary class."

She pouted. What's with that have fun part? Did he just wish for her taking another supplementary class? "I don't wanna attend that supplementary class." She murmured.

He raised a brow hearing her statement. "Is it that bad?"

"Yes, it is, and it makes me unable to go home with Tsubasa." She took her pen and started scribing randomly on the last page of her note book. She drew Yamada-sensei's face and gave a big cross on it. Next to it, she wrote Yamada the Evil.

He leaned his back onto a bookshelf behind him and sighed. "That guy again… He's old enough to take care of himself."

"But he dresses as a girl." She replied, still working on her hateful doodle. She had just added pair of devil horn on the teacher's head.

"Even a real girl can take care of herself." He contravened.

She stopped drawing, unconsciously tightening her grip to the pen. She took a deep breath then said, "Still, it's my duty to protect him. You know, he cross-dresses as a girl not because he wants to. Our family's tradition forces him to. Every single member of the family has to obey the rules no matter what."

"That's absurd," Zaizen commented. He stopped for a while then added. "Don't tell me you're doing this because of that what-so-called tradition too."

She shook her head and then smiled to him. "Of course no. I do this because I simply love him. He's my only brother after all."

He didn't say anything again in reply. After a quite some time watching her doing nothing than silently ranting on her teacher, he gazed on her books then straightened his back and walked away.

She blinked in confused as he disappeared behind bookshelves. Why did he left like that? Had she said something strange? She shrugged. That guy was really mysterious. She didn't understand him, his acts and the way he thought.

'Nah, forget about it, you need to concentrate on your study!' She reminded herself and turned to the table. Not only she still have unfinished math homework, she also had to redo the English one. She looked down at her note book and sighed.

It seemed that those boys really had bad relationship. Zaizen had also looked irritated when she had mentioned Tsubasa's name. What exactly had happened back then when they got home together? Had their relationship been that bad from the very beginning?

Oh great, now she was distracted again…

She pinched her own cheek. 'Concentrate, Tsubaki! Concentrate!'

"What… exactly are you doing, Senpai?"

She looked up upon hearing the question and suddenly she found Zaizen was there again. He put some thick books, including English-Japanese and Japanese-English dictionaries, on the table and sat down on a chair opposite to her. He then took her English book and flipped through the pages.

"You know it's obviously impossible for me to substitute you during your English test…"

Really, she didn't understand him, his acts and the way he thought. However, one thing she knew, studying at the library during the lunch break wasn't a really bad idea at all.

Does this mean he willingly helps her studying? You guess~ XD

I know this chapter is too short. At first I wanted to add another scene but I changed my mind because I thought it would be strange. Trust me; it's much better like this though, again, it was too short. ^^;

Anyway, I'm very sorry if you find him OOC.
