Stepping on Roses, Volume 6 by Rinko Ueda

A rags-to-riches romance from the creator of Tail of the Moon!

Poor Sumi Kitamura... Her irresponsible older brother Eisuke keeps bringing home orphans for her to take care of even though they can barely afford their own basic needs! Just when Sumi's financial problems become dire, wealthy Soichiro Ashida enters her life with a bizarre proposition: he'll provide her with the money she so desperately needs if she agrees to marry him. But can Sumi fool high society into thinking she's a proper lady? Moreover, is it worth giving up everything for this sham of a marriage?

Pronouncing Sumi and Soichiro's marriage superficial, Nozomu becomes even more dogged in his quest to make Sumi his. As Nozomu teams up with Natsuki to bring Soichiro down, Soichiro finds his carefully arranged life unraveling before his very eyes...
