Lieutenant General Euclid Von Wisteria is a well-known beastman cold and calculated man nick-named the "Bespectacled Ice Lord." Those who are beastmen are known to be devoted to their mates for the rest of their lives. At the same time, Musca has been living in the castle as a servant to the nobility for some time and has been looking for a peaceful life as a normal woman. However, during the festivities ensuing at the end of a long war, Musca has definitely had too much to drink... and finds herself in bed next to the Bespectacled Ice Lord himself!
