Kakene Nashi no LOVE Torihiki

Since Ami Kirisawa's father passed away, she's had to make it on her own. Now she's built a reputation as an enterprising young woman who will do anything for money. However, when Ruka Hakomori (of the Hakomori Financial empire) makes assumptions about how much of Ami his money can buy, Ami fearlessly proves him wrong. Ruka decides he wants her to help him get out of a marriage interview, but opposing Ruka's ruthless parents isn't going to be easy, no matter how fearless Ami is.
