The Un Familiar Brother
¹⁵UFB

..."You are like a side-seeking formula using the cosine sine rule, confusing as well as confusing at the same time."...

...Un Familiar Brothers...

...🫐🫐...

Two girls are seen busy struggling with sheets of HVS paper scattered. Pack books were scattered on the table, some were open and punctuated. They deliberately took a seating position that was quite far from other library visitors. As a result they decided to sit in a corner, flanked by bookshelves and large windows that showed a view of the basketball court below. Deliberately sitting there, because they want to focus on doing the tasks given by their teachers.

"Udah not yet? How long, Cha?" asked the girl with the back hair, curious. Since then, his best friend has not had the slightest response. It was then shocked. "New formula? haven't you broken a single thing?"

"Mumet, the formula also forgot again hehe," kekeh his interlocutor while grinning the horse.

"Basic. Where, here I see."

In the spirit of 45 Cacha swiped his taskbook in front of Nara. Letting the smart girl correct a job that has been in the last forty minutes trying to do on her own. However, the result is so nil. None of the questions were answered.

*Sinus rules formula

BC/sin A

Ac/sin B

AB/sin C

*Cosinus Rule Formula

AB \= AC + BC - 2 × AC × BC Cos C

AC \= AB + BC - 2 × AB × BC Cos B

BC \= AB +AC - 2 × AB × AC Cos A

"This is what Cosinus' formula is wrong, Cha."

"Ah, what a real feeling?"

Nara stared at her best friend for a moment, before pointing the pen in her hand at the paper.

"It should be that AC has a square of ², same BC also has a square of ². That's it!"  nara said while correcting some formulas in Cacha's notebook.

a2 \= b2 + c2 - 2 bc cos A

b2 \= c2 + a2 - 2 ac cos B

c2 \= a2 + b2 - 2 ab cos C

"Ah yes, khilaf euy," chuckles Cacha. He grabbed tip-x from the pencil. Remove the wrong part with the white liquid.

"You're not careful, plus...."

"Slowly," interrupted Cacha by twisting the eyeball. "Western memory yes, my brain capacity is only a few Gigabytes, different from the same lo brain capacity nyampe 1 Tera." Keto.

Nara smiled faintly, then clicked Cacha's wide forehead slowly. "Well, what is the parable from where to try?"

"From Indonesian literature lessons" replied Cacha. "But the truth is even more bitter than the parable."

Nara shakes her own head every time she sees the friend humbling himself, just because he is less responsive in absorbing learning materials. Though everyone also has the capacity of their own capture.

The two then returned to work on the task while chatting, to the point that no one came near. Steal the attention of other library visitors, out of curiosity about its appearance.

"Why did you leave alone?"

Nara looked up, looking at the owner of the baritone voice who had just spoken up.

"Fear late, Brother." Nara answered at that.

"Lo don't believe me?"

"What does Brother mean? Didn't Brother yesterday just talk nonsense? why am I waiting for something uncertain. If you're late for school, I'm the one who's bothered."

Arga looked at Nara sharply. The look on his face implied a dislike for the answer.

"Go back to school with me!"

"I have a group of OSIS."

"Gue wait!"

"Later home late. There is a sekbid briefing as well. So...."

"Gue wait in the parking lot. Don't try to escape!"

Nara looked at the back of the handsome young man who had started to move away. He had not had time to reject the offer that spiced up the imposition, the perpetrator had already waltzed away just like that.

"Nar, are you actually offered to go to school with brother Arga?" cacha asked in disbelief. Since then just gawking cengo see the interaction of the two.

Not only was Cacha curious, many other pairs of eyes also seemed curious about Arga and Nara's relationship.

"Later I'll tell you, now it's his job."

"Yes promise?" urge Cacha.

"Yes, promise."

...🫐🫐...

"Elahh, what's this formula to memorize it? I don't understand seh?!"  Ketus the young man who was doodling the HVS paper.

Both of the stairs had not stayed silent since, taking pictures also ruffled her hair in frustration. The same with his feet wrapped in converse shoes, also do not stay still. Every now and then he kicked the pissed-off leg of the library table that is now occupied.

"What formula is it, Ki? Just raucous from earlier."

"Feel feeling once fitting class eleven semester two ever taught this material deh? How, I forgot, huh?" timpal Iki again.

"The formula of what is the geblek, here let me who fuss. I'm not, smart!"

"Here, smartass you are, son. Eleven-twelve brain capacity is the same me too!"

"Ehh, I'm a big idiot" upset Libra while seizing Iki's book. "It's easy, just stay a few times."

"How do you mean? It was clear there it had to be added, reduced, continued to be multiplied or cos, siah geblek."

Libra clucking. "Eleh, this is a new formula, Ki. Take it easy, the important thing is that there is a result."

"Rules from where, time can make its own formula? O'on sia!"

"From me, the formula of the latest edition," arrogant Libra. It was his ninja path if unable to answer his math assignment.

The conversation of the two paused for a moment as someone suddenly stood in front of them.

"Which art?"

"Ehh, Medusa, where do I know the leader where. Who likes to drug him, right there, how come to us anyway?" answer Iki sewot.

"Don't look at you, we're on duty. Have eyes that are not made?!" Tympanic Libra, spicy.

"Which art?"

The beautiful girl in Angkasa High School uniform turned, asking Orion who was focusing on staring at the mobile phone screen. Orion simply glanced indifferently at him, before responding.

"What?"

"Gue asked, Where is Arga?"

The face of Orion's flat seemed to show no response. However, I glanced at the door. Sure enough, when Alexa turned her head, the figure she was looking for was standing with her body leaning on the door frame while folding both hands in front of her chest.

"That's what you're looking for" Orion said. He also resumed playing games on mobile phones that had been delayed because of Alexa.

Alexa immediately left Orion, rushed to the figure that lately difficult to find. Although yes, they sometimes go to school and go home to school together. That's even if he is forcing with a little tips and tricks.

"Where are you from? I've been looking for you since."

His interlocutor's sharp netra rolled aside, staring indifferently at his interlocutor.

"It's none of your business."

"You why the hell? You've changed, Ta!" alexa said as she looked at the handsome young man before her questioningly.

Alexa is quite uncomfortable with rumors about Arga who has a new toy. Initially Alexa thought it was not something to worry about. However, the more intense the rumors about Arga's proximity to the toy blew. Making feelings of discomfort and tension increasingly strengthened in his heart.

"It must be because of that poor girl, right?"

Arga indifferently. "It's none of your business."

"So right?"

"Don't ask too many questions!"

"She's just a poor girl who capers with you Ta. He must be envious and want to take you away from me!" alexa said.

Lie if he is not jealous about the closeness of Arga and his new toy. He is quite worried, if left for a long time then fear grows seeds called love.

"It's none of your business!" hiss Arga sharp, he then passed towards his three companions. I don't care about Alexa.

"You can't be like me Ta, I love you. We are ... brothers."

Arga's steps stopped at that very moment. His sharp onyx looked gleaming furiously. All eyes in the room are also now focused on the second most wanted SMA Angkasa.

It is no longer an open secret if the toxic blood relationship is not just a figment. Alexa is very possessive on Arga who incidentally shares the same blood with him. Most schoolgirls who like Arga even prefer to retreat alon-alon, because Alexa's attitude is too aggressive if there are students who dare to approach Arga.

Alexa does not even hesitate to do bullying on the schoolgirls who managed to get close to Arga, although she knows that Arga does not take interest in any girl. Not only is her beauty respected, Alexa also became famous for having a personality that is feared.

Alexa swallowed her hard-earned saliva as the black onyx Arga looked at her so closely. The beautiful young man was also now back standing right in front of him. Staring at Alexa with a ready-to-kill look.

"We do have a blood relationship with me, but that doesn't mean you can interfere with my life."

"...."

"Lo doesn't have the right to set me up. Especially to disturb him. Take it well, Alexandria Natadisastra."
