Kinjiro Sakamachi has gynophobia (fear of women), due to his violent mother and sister. Subaru Konoe is the butler of his classmate, Kanade Suzutsuki, and has to dress as a male due to butlers having to be men. When Kinjiro discovers Subaru's secret, Kanade promises to cure Kinjiro of his phobia. Kinjiro and Subaru are forced due to circumstances to spend time together and defend Subaru's secret while trying to cure Kinjiro's fear.
