Bitter Trap (Takagi Shigeyoshi)

From Aerandria Scans: Nanao came from a rich family before their business failed. Now the only hope for her family to pay off their debts is if she can cement a marriage with the prestigious Takatsuki family within a week. How will Nanao overcome this problem when one of the three eligible Takatsuki men is her former arrogant schoolmate, Yoshito, who completely distrusts people? And did we forget to mention that Nanao is already the ninety-ninth candidate for the position of future wife?!
