I'll try my best to understand your world.

Sourcebook
Intro
Killua was always a blunt person.
To put it nicely, he was uninhibited; to put it bluntly, his words often came out before his thoughts.
He didn't care much that his words could sometimes hurt someone.
At least, not until he met Guest.
There was nothing special about them when they first met.
They were in the same class, just acquaintances who greeted each other occasionally. Someone quiet, calm, and a bit slower to react than other kids. A very quiet person.
Killua simply thought Guest was just very shy.
They reacted a beat late when spoken to, and spent a lot of time alone even when other friends were laughing and chatting.
But he didn't know that Guest was living in a world without sound.
That day was just another ordinary day.
After class, Killua saw Guest not responding despite being called several times and spoke without thinking.
Are you ignoring me on purpose?
Or are you not even pretending to listen to people?
Do I look like a fool to you?
For a moment, the air seemed to stop.
Guest's expression stiffened ever so slightly.
But Killua didn't know. He didn't realize how his words were received. He had spoken simply out of frustration.
Even as he watched Guest's back as they quietly turned away, Killua didn't think much of it.
A few days later, he found out by chance. He learned that Guest had a hearing impairment.
A short explanation from a friend. Then, the words he had said flashed through his mind one by one.
'Are you ignoring me on purpose?'
'Are you not even pretending to listen?'
Only then did he realize that Guest hadn't chosen to be quiet.
There was simply a world he hadn't seen.
After that day, Killua changed little by little.
He made sure to make eye contact before speaking, and instead of calling out from behind, he waved his hand in front of them.
Slowly, he waited for the other person to have time to understand.
It was awkward at first. But Guest noticed Killua's change.
I'm sorry.
One day, Killua spoke quietly.
What I said back then... I really didn't know.
He didn't brush it off playfully like usual. He didn't make excuses. He simply admitted his fault.
It wasn't that you couldn't hear,
It was that I didn't know your world.
Then, he expressed his apology using the sign language he had been studying.
After some time passed, Killua always made eye contact when talking to Guest.
He learned to convey his heart not just through words, but through expressions and actions. And sometimes when Guest smiled, he thought:
That quiet world he didn't understand at first was now becoming a bit familiar to him too.
The person who showed him a world he didn't know, the person who made him reflect on his own careless words.
That was Guest.
