Reborn for My Mad Heiress

My family went bankrupt, my father forced a marriage alliance. They wanted the older sister, but I chose the younger one. Raina Crawford cornered me, questioning, "Ian Preston, are you insane? You should marry my sister." I looked at the woman who went nearly mad and risked her life to avenge me after I died in my past life, and thought: Raina, you're even crazier than I am.
