He muttered the steps under his breath.

This whole math thing was hard.

The only math he had to do back in Grian was his ammo supply, how much time he had left, calculating distances between checkpoints and the angles he had to shoot at if his target was far away.

He was positive that he didn't have to know how to solve for a triangle for him to survive in the world.

He already went 10 years without that knowledge, he was sure that he could survive the rest of his life without knowing that bit of mathematical knowledge.

His neck prickled as someone stared at him.

He looked up, and blinked in surprise when he realized that it Yeona who had been staring at him.

He couldn't tell if she was more flustered that she was caught staring, or the fact that he turned around to look at her without hesitation.

Now that he thought about it, Major Kang had told him that it was seriously creepy that he could tell exactly who was staring at him.

Oops?

Was this what the Major meant when he called him emotionally and socially stunted?

Probably.

"Uh," Yeona was flustered as she tried to make conversation, something that always happened when he surprised her. Seokju's eyes were flickering between Ijin and her, giving them an odd look," What language were you speaking right now?" He must have done that odd habit of his again.

Hm.

That was a good question.

Oh that was a really good question.

You didn't ask questions back at the camp. You just answered questions, followed orders and tried to survive. Even as a mercenary, it was the same thing.

So he never asked what language he was learning after the crash.

All he knew was that if he wanted to live to see another day, he needed to know what his trainers and superiors were saying. Its really weird how no one ever mentioned what language he was learning. (Then again, its not like his superiors would have to mention what language they were speaking in debriefing.)

Not to mention, for a long time, he wasn't in the mental mindset to question everything that came across his mind unless it was related to his mission or survival. To make things better, he was and is still reserved, so even if he wanted to ask a question, he just would have swallowed it instead.

The more he learns about everyone's childhood.

The more he realizes just how fucked up his childhood was, and how important it was that he kept his former occupation a secret.

"I don't know."

Great, his friends were staring at him again.

"No one told me what language I was learning when I was a kid."

Seokju blinked slowly. It looked like he was having an aneurism, which was fair, before he said slowly," And you didn't ask…?"

"No."

"…why not…?" Jaehyung said slowly, he looked just as confused as everyone else.

He shrugged a single shoulder before he turned back to the asinine math he needed to learn.

"It was never a good idea to ask questions."

Hyeokjin put his head into his hands and sighed a soul-weary sigh.

"This jerk is going to be the end of me."
