A strong-willed high school girl and a hot young scion of a business empire can't help trying to outwit each other every chance they get... But could these opposites be conning themselves out of the perfect match?!

After her older sister refuses to go to an arranged marriage meeting with Takane Saibara, the heir to a vast business fortune, high schooler Hana Nonomura agrees to be her stand-in to save face for the family. But when Takane and Hana pair up, get ready for some sparks to fly between these two utter opposites!

A hospitalized Takane drops a major bombshell on Hana, and she doesn't know if he's serious or not! In typical Takane form, he overdoes things, and Hana is at a loss as to how she should deal with the news. Could some advice from love rival Rino actually help?
