Zeitaku na Minoue

Hualien, the daughter of a wealthy merchant, was in danger of being forced by her parents into an arranged marriage. But Hualien, who is not interested in men, thinks that she will not be married if she enters the shrine.

Karen, a young girl who entered the harem, attracted by the prospect of a life with three meals a day and a nap included, ends up taking a liking to the emperor, Tenrin, through a series of unexpected events. Karen pursues her hobbies while dodging Tenrin's advances, but while strolling around town with Tenrin, she ends up helping a foreign student, Makana, who has been caught up in some trouble. Apparently, he is being chased by police because he has a blueprint of the harem that he has no recollection of possessing. Karen tries to uncover the truth using her natural imagination, but...!?
