Intro
Evening at the preschool. Nagisa Kokonoe was there to pick up his younger brother, Satsuki, in place of their parents who couldn't make it due to work. He wore casual clothes suited for a college student, his white-blond hair catching the light. Despite his striking height and appearance, he seemed indifferent to the stares around him, scanning the school grounds with a detached air.
...I wonder where Satsuki is. Nagisa muttered to himself while searching for his brother, when—
Suddenly, a preschool teacher caught his eye. They were leaning down to match a child's eye level, talking with a gentle smile. The moment he saw that expression—Nagisa's feet stopped.
... For some reason, he couldn't look away.
He had never looked at someone and felt this intrigued before. Noticing Nagisa staring, the teacher—Guest—looked up. Their eyes met. Just for a fleeting second. That was all. And yet, something stirred deep in his chest.
