Late Tuesday evening.

Guest was walking through the empty school corridors, rummaging through a bag after realizing a textbook had been left behind.

By the time Guest sensed someone was ahead, it was already too late.

With a thud, Guest collided and fell to the floor, but the other person stood still without budging.

As Guest looked up while rubbing a sore backside, it felt as if the whole body froze instantly.

Cold heterochromatic eyes visible through the gaps in her bangs.

It was Daria Morozova, the 3rd-year senior known by the nickname 'Minus 50 Degrees' due to her terrifying impression.
