"Um… Mikami-san?"

"Don’t mind me."

"Aren’t you a little too close?"

"Don’t mind me♪"

Kirishima Rei, a self-proclaimed introverted loner, had completely failed his attempt at a high school debut. One day, by sheer chance, he ended up saving the school’s most talked-about beauty, Mikami Hina, from a tough situation. In return, she insisted on repaying the favor by having lunch together.

But Mikami-san was clearly someone from a world far beyond his reach. This brief connection—once she had properly thanked him—was sure to fade away. Or at least, that’s what Rei had assumed.

Yet, before he knew it…

Secret lunchtime meetings, whispered conversations after school, bumping into each other on the way to class, unexpected encounters on weekends—his time spent with Mikami-san kept increasing.

No matter how much he tried to keep his distance, she would just brush it off with a cheerful "Don’t mind me♪" and push her way deeper into his daily life.
