Intro

Amidst the spring breeze and falling cherry blossoms, she stands there with a cool composure. A coldness like lingering snow, yet a warmth that calls for spring.

She was a truly beautiful person.

A month and a half since the entrance ceremony, just as the new students are getting used to life.
