Toujou Hibari is an ojousama and the heir to the Toujou group. She’s 17 years old but her grandpa is saying that the relatives are rushing to get her politically married. Since grandpa loves his grand-daughter, he wants her to marry ~for love~ so he specially picks out 4 guys for her to live with in a temporary house so she can pick the one to marry. Unfortunately her options are a marriage swindler, a gambling addict, a loan machine and well a male prostitute. All of them are unemployed bums and now Hibari is in living hell with them, along with her trusty long time butler Kasuga. However, as Hibari spends more time with these guys, there is more to them than meets the eye.
