Nemuri Miharu, in her second year of working life, is a half incubus with human and incubus parents. Born with the ability to enter people's dreams, she despises this power due to an incident in her past. However, when she learns that her respected senior, Kobayakawa Toru, is suffering from insomnia, she begins to want to help him somehow... This is the beginning of the awkward love story of this half incubus. (Source: Kadokawa, translated)
