Tomomi works in a company that's supposed to provide her with board and lodging, so when she's suddenly told to temporarily leave her apartment, she's at a loss. With nowhere to go, she accepts the offer to share a room... with Ryou, a handsome but unreadable man. In exchange for a place to live, she has to take care of the housework, but no one told her she had to become a host as well! On top of that, there's another secret condition she must fulfill... and it involves getting very, very close with Ryou!
