This is a "what-if" story.
Welcome to an alternate version of Little Busters! The field trip ended without incident, and Kudryavka Noumi and Riki Naoe are now a couple.
Due to an issue with the boys' dorm renovation, Riki is left without anywhere to stay over summer vacation. He's at a loss until Kud tells him...
"I'm, um, still looking for a roommate..."
Thus begins Riki's summer with Kud, which brings them all sorts of new missions. What impact will these experiences leave on them...?
