"Have you ever tried healing with your eyes closed?"

You blinked. Healing with my eyes closed? It wasn't something you'd ever tried before, heck it wasn't even something you dreamed of trying. Healing requires your full attention. Nen was life energy - not magic, ironically enough. Your eyes had to be open and alert, to ensure you weren't healing an injury incorrectly.

"Uh...no?"

"Why not?"

"Well," you shuffled nervously in your spot, "I've never tried it before. What if I mess up? Healing always requires my full attention, I can't even imagine closing my eyes, if I'm being honest."

Wing smiled, "(Y/N), it seems like this is the next step in your training. The nen-bond is like a condition; While your eyes are open, you can heal to the best of your ability, but people you might not want viewing your surroundings will be able to. But, if you heal with your eyes closed, no one will be able to see anything."

You frowned, "But what if I need someone to see my location?"

Wing gave you a sympathetic look, "You'll have to decide if you want to open your eyes or not if that situation arises."

"I see." Your gaze flickered to Killua, then back to Wing. "How can I practice healing with my eyes closed? Or should it be a spur of the moment thing? Wouldn't that be dangerous?"

Killua let out a short 'Tch' under his breath as he stood from his seat, "Wing-san, you can slice through anything with your nen, right?"

Wing nodded, "Yes, I suppose so."

Killua pulled off his sweater, "I've got your practice right here, (Y/N)."

Immediately you began to shake your head, "What? No, Killua that's crazy, you could get hurt."

He smirked, "But you can heal me."

Speechless, you gaped at him.

"I can do shallow cuts," Wing interjected, "the pain will be very minimal."

"Ah," Killua sighed, "don't forget that I'm also a former assassin. Tiny cuts like that are nothing."

For some reason, hearing him say that didn't make you feel much better. You frowned and looked up at him with sad eyes. You didn't want to hurt him. Not like you know he's been hurt before.

"(Y/N)," he whispered, like a sweet hum from his lips.

"What?"

"Stop thinking so much. Just do it. It won't hurt and I know you'll heal me anyway, idiot."

He averted his eyes away from you. Is that a faint blush on his cheeks?

You smiled, "Okay."

You sat down by Killua's side, palms already hovering over his form in anticipation for Wing's cut. Killua knelt next to you, his right arm outstretched like a target.

"(Y/N)," Wing warned, "don't be surprised if it's a slightly overwhelming experience. Closing your eyes heightens your senses more."

You took a deep breath. I can do this, I have to do this.

"Are you ready?"

Killua nodded, "Ready."

"..Ready.."

It happened faster than you thought it would. Wing brought up two fingers, pointed it at Killua's arm, and then boom, a thin sliver of Killua's skin was split open, dark red blood spilling out the side fast. However, while Wing was fast, you were fast too. In an instant, you closed your eyes and grabbed Killua's arm tightly in the gold aura that encapsulated your hands.
