Ookami-san ni Oyasumi.
おおかみさんにおやすみ。
A princess from a minor kingdom is arranged to wed a werewolf prince from a neighboring land, taking the place of her sister who declined the union with a family known for their savage reputation. Expecting a monstrous, furred figure, she is surprised when her new husband appears as a tall, attractive man instead of the beastly form she anticipated.
