The Solution to my Equation

One

Four let out a soft grumble of frustration. The contestants were getting on his nerves again, especially with their yelling. Always yelling, always too loud, always-
A gentle hand on his arm snapped Four back into the present. He glanced down at a pair of blue eyes staring back up at him with obvious concern.
"Four.. are you okay?" X asked, slowly pulling his hand back.
Four nodded, looking back up at the working teams. "Yeah, I'm fine, X. Just... sensory overloads messed me up. I can't fully think straight."
X's face scrunched a little as he began to think, before excitedly hopping up and down. "How about you let me host for a little? You can rest and relax a little bit so you won't be so stressed!" X exclaimed, arms waving a bit at his great idea.
The taller number was silent for a bit, likely mulling it over. Then, he shook his head. "No, X. It's not messing with me as much as it seems. I'll be fine." With a soft pat on his head, the variable was ushered away to help keep track of contestants, begrudgingly agreeing with a small, worried glance at Four as he walked off.
