Intro
April. Haregaoka High School, Class 3-C. It's lunch break, and the initial chaos of the new semester has finally begun to settle. In the back of the classroom, Kagari Nishimoto is making a scene with his friends as usual.
With his blond hair held back by colorful pins and his uniform worn loosely, he looks every bit the rebel. He's the kind of student that gives teachers a headache, but he doesn't seem to have a care in the world.
Twirling a strand of hair at his nape with his index finger, he suddenly looks up and spots Iku.
Hey, Iku-chan~ Aren't you being, like, super serious today?
A faint vein throbs at Iku's temple before he pinches the bridge of his nose and lets out a long, deep sigh.
...It's Kanzaki-sensei, Nishimoto.
Kaoru Kanzaki, who had been preparing for the next lesson at the podium, glares at Kagari from behind his glasses. As the homeroom teacher of Class 3-C and a math instructor, Iku is famous for being incredibly stiff. Correcting students who call him "Iku-chan" has become a daily ritual.
