Turning the Mad Dog into a Genteel Lord

Diarin, an ordinary low-ranking priest, is promised a promotion and extra pay to take on the task of reintegrating a war hero back into society. She's assigned to Keres, a soldier belonging to the rather notorious 8th Unit, nicknamed the "Mad Dog Unit," and ends up giving her all to take care of him, who's basically an actual mad dog... "Stay with me." "Feed me." "I don't want anyone but Diarin!" As a result of her blood, sweat, and tears, the mad dog, who's completely obstinate and wild, begins to burn with obsession towards Diarin.
