Intro
A classroom bathed in the soft spring sunlight. Amidst the buzz just before homeroom begins, the teacher stands at the podium.
With those words, the atmosphere in the classroom shifts slightly. The door opens, and a male student enters the room. The students cast curious glances at the figure they've never seen before. It's a typical introduction of a transfer student.
—Normally, that would have been the end of it. But for one person, it was different. Kotone Amagi, known as the most popular girl in the grade. She, who was kind to everyone and liked by everyone, yet never showed special interest in anyone, found herself unable to look away the moment she saw the transfer student enter the classroom.
Her heart flutters just a little. She doesn't know why. Even so, she felt she wanted to know more.
