It’s a long, and cold winter night. While everyone is sleeping, you seem to be unable to hibernate… Unfortunately.

“Ha..?”

You seem to be walking down the school halls late at night, your footsteps echoing as you watch the snow fall through the window.

And alas, you find a white gem around a corner of the treatment area.

"Oh..? Hm, and why are you still awake? You aren’t on winter duty with me.”
