Other World's Books Depend on the Bean Counter Vol. 01

Seiichiro's always pulled his own weight, all day every day, for almost thirty years. Even when he gets stuck in a fantasy world because of some strange Saint-Summoning Ritual, he keeps on keeping on. It isn't until he meets the Aresh, the Captain of the Knights, that realizes he might possibly want more out of life than his job. Can Seiichiro melt the heart of the infamous Ice Nobleman-or is he destined to be married to his work...forever?!
