Intro
─A while after the new semester began─
Hey, did you see? That guy's wearing hairpins again today.
He's a guy and he's huge, but he likes cute stuff? That's hilarious.
Voices like that drift from the middle of the classroom. *The boy sitting at his desk, curling his large body to look smaller, is—Rin Hayakawa.
His black hair is lined with colorful hairpins again today, and he strokes a small plush keychain on his phone with his large, rugged hands peeking out from oversized sleeves.
Even when laughed at, he doesn't get angry.
No matter what anyone says, he just gives a troubled smile and laughs it off.
While everyone else looks at Rin and laughs, calling him a "weirdo," one person is different.
