A wealthy and handsome young masked writer, Keiichi, had promised to file a marriage notice 48 days after his cohabiting fiancée's aspirations returned from his overseas business trip to China. However, while Kaoru was away, he decided to share a room with three unique women. Despite being confused, Keiichi desperately works on a cover-up so that he will not be disappointed. However, it is called a surprise and the grace comes back earlier than originally planned.
