The Heiress and the Chauffeur is a historical romance manga. I bought my copy of this volume new.
Review:
Sayaka's father arranges a marriage meeting for her with Akihiko Tachibana, the coldly business-minded third son of Earl Tachibana. In the process of turning him down, Sayaka accidentally causes him to fall for her. This could turn into a complicated love triangle, but since this is the final volume of the series and it's time it's time for Sayaka to start catching on to her own and others' feelings, things get resolved more quickly than that. Somehow, the author still manages to fit in a few surprises, though.
