"Nyru fu fu... Tears don't suit you, Nagisa-kun~"

"Sen...sei...?" Nagisa couldn't help, but shiver faintly as he squeezed his eyes shut. He didn't want to look up only to see nothing. It wouldn't be the first time his mind played such a cruel trick on him.

He scoffed to himself, shaking his head in dismay. "What is wrong with you, Nagisa... Imagining things at your age?"

"How rude! I'm as real as I can be!" A little jolt ran through him and he smiled despite himself as he remembered a similar response years ago.

"Um... excuse me... Is this guy some kind of, uh, alien who's come to, like, destroy the planet?"

"How rude! I was born and raised on Earth!"

Shaking his head again to clear it of the past, he still refused to look up. "If you're real... tell me something only you would know." Tch... why was he doing this, as if this was actually happening-

"You never wanted to be referred to by your last name because at the time your parents were separated." He stiffened faintly at the quiet reply.

A gentle touch brushed against his chin before his head was pushed up. He squeezed his eyes shut, but a light touch carefully coaxed them open again.

"One of your first major attempts to kill me was a murder-suicide."

A little tremble washed over him as their eyes met. Despite his quiet, serious tone, his ever-present grin was wider than ever.

"I'm going to be a teacher." He jolted as his own words were reiterated. "I'm not fast like you, or invincible like you, or smart like you..."

"...But I want to be a teacher like you..." He finished, tearing up. The questions 'how' and 'why' crossed his mind, but neither matter right now as he shot up and threw his arms around the best teacher he ever had.

"Sensei!"
