Fang never though that he would deal with Taufan's obnoxious big brother.

It was an ordinary day after school. Fang sat under a tree while working on his math homework for tomorrow. That's until...

"Fang!"

Fang looked up from his book. He could saw two Taufans running to him... Wait. Two Taufans?! Clone?!

"Hey, Fang! Check it cool!" said the first Taufan. "This is my big brother, Halilintar." The Taufan gestured to the 'clone'. "Isn't he shizzy?"

Fang let out a sigh of relieve, knowing that that's not a clone of Taufan. One Taufan is enough, thank you.

"Ugh, I am Fang. A pleasure," Fang said with a monotone voice. "Then, how come you never told about your brother, Taufan?"

Taufan scratched the back of his head while grinning. "Well... Since we've always been raised separately across the world, he had to spend more time with our uncle Luigi in Italy, so he's become kind of a jerk." He looked at Halilintar who kept looking at the ground. "Right? Now say 'Hi' to my friend!"

With a lazy face while waving his hand up-and-down, Halilintar said, "Get lost, you damn four-eyes."

Fang jaw-dropped. "Ugh…"

Taufan frowned. "Oh, boy, it's hug time," he muttered. He then hugged Halilintar viciously as he tried to pull him away from Fang.

"Would you stop it with your hug therapy, already?!" Halilintar shouted as he tried to wiggle free from Taufan's hug.

Meanwhile, Fang just watched them, doesn't know what to say to them. "I'll never understand twins," he muttered to himself.

Another day. Fang decided to borrow some books from the library. He just came out with some books about sport (especially soccer), that's when Halilintar decided to showed up.

"Okay, Mr. I'm-so-popular," the Halilintar said. "What you do to twist my brother's head around so bad?"

Fang looked up toward him. "Uh, what do you want?" he asked, doesn't really get how Halilintar found him.

Halilintar just crossed his arms in front of his chest. "Damn you! Don't play dumb with me! That's my brother's job, and I know you've got some plan for him that's sinister, and sure, your highways don't have speed limits, but that doesn't give you the right to criticise the man's microbrew the best thing, four-eyes!"

"Stop right there!" yelled Fang. He has to stop Halilintar before his head explode. "You can't blame me for what—"

But, Halilintar didn't listen to him. Instead he took out a bucket filled with tomatoes (where did he get it? Nobody know...) . He took one tomato and raised it above his head. "This weatherman is predicting a 99% chance of tomato-storm, and it's coming right at you!"

And suddenly, a boy named Adu came out from the girl toilet a few feet behind Halilintar. "I have finally succeeded in spying Fang secretly," he chuckled. "Now, I can take him by surprise—"

Halilintar's face paled. He dropped his bucket and his behind Fang, using Fang's jacket as a head cover. "ARGHHH! IT'S ADU! Protect me!"

Adudu gasped when he saw Fang and Halilintar. "Oh, no! It's Fang!"

Later that day after PE lesson...

"Hey, four-eyes!" Fang turned around to see Halilintar glaring at him. "I have a surprise for you!"

Fang rolled his eyes. "Great, what is it?" he asked mockingly.

Halilintar smirked evilly. "I have created a secret weapon for such singular purpose and stealthiness that you will be helpless to it's powers."

Fang just raised an eyebrow as Halilintar raised the object. "Mustache." He burst into laughter, holding it in midair. "HAHAHAHA! You look so very stupid! Like some stupid hipster at a high school party!"

"Uhhh." Fang looked at him questionably, as if debating whether or not to call an insane asylum. "You do realize that it looks like you are the one with the mustache from where I stand, correct?"

Halilintar shrieked. "Look away! No! Close your eyes! Don't look at me!"

~Fang: HetaBoys~

Later at Halilintar's and Taufan's home...

"Wah! No fair!" Halilintar wailed to his younger brother. "My secret moustache totally backfired on me! I quit!"

"Aw, don't cry, Halilintar," Taufan comforted. "Fang doesn't care if you have a mustache or not. He's really a nice guy, trust me! He's really nice when it's to his advantage and he knows how to keep things clean and organized. Plus he's strong and pretty, more than anybody! And that's got to count for something in this day and age. Also, Fang's quite cute!" he giggled. "And laughing is good for the heart."

Halilintar stopped his crying to look at Taufan. "Taufan, just once, can you say nice things about me like that?"

Taufan's smile disappeared. He backed up. "Uh..."

A horrified look appeared on Halilintar's face. "I HATE YOU SO MUCH!" His voice was so loud, birds flew off the roof of the building they were in. He stormed to his room.

"Where are you going, big brother?"
