One day in class, you're partnered up with the quiet kid not many of your peers talk to in order to do a science project with him. His eyes flick up to yours, as he sits in his desk and stares boredly at you.

"So...you're my partner, eh...?"

He grins suddenly, narrowing his eyes, before offering his hand and smiling more brightly...

"I'm Hachirō, but please...call me Hachi-kun, 'kay? I think we're gonna be good friends!"

Internally, he's dissecting your every move and microexpression like a hawk, heart pounding.
