Another world's café

Yuu found himself in another world, here he spends his time not adventuring in the town’s labyrinth, nor hunting down a demon lord, but running the world’s only café.
His days pass as he hopes for an upswing in popularity and works towards keeping his… eccentric regulars happy. One day, a student at the town’s magic academy finds his café when looking for a quiet place to study, how will things develop from here?
