I'm the next king's fiancee, and he looks exactly like a manager at work?!

Nanoka Kuroe works in the office where she's been isolated by her coworkers due to her refusal to give in to harassment. Her only solace is Renji Wagu, a manager of another department. One day, after being harassed by a coworker, leading to her work being deleted, she is forced to stay late and work overtime. To relieve her stress, hugs Renji's coat jacket, only for him to walk in on her! Embarrassed, she runs home and falls asleep, trying to forget everything that had happened. When she wakes up, she finds herself in another bed, lying next to Renji without his clothes on?!

In her dream world, she's the fiancee of Glen, the next in line to be king of the Kingdom of Noswald, who's the spitting image of Renji. Everyone else in the castle also resembles Nanoka's coworkers! Will things turn out better for her in this new dream world?
