Trama
Yuki sits in an after-school study session, working hard on classic lit (one of her worst subjects). Mii-kun stops by to help tutor her senpai, and as she recites from "An Account of My Hut" Yuki exclaims that old books are like letters from the past. Inspired, Yuki rounds up the School Living Club and the four girls sit down to pen a message to the world.
