SSIS-571 In exchange for my husband's ¥80,000,000 debt, I am raped by my father-in-law every day to satisfy his desires.

After six years of marriage, the innocent Sae had been devotedly supporting her husband, Hiroki. Due to the impact of COVID-19, their company turned into a deficit, and Hiroki was constantly running around for financial management. Seeing this, Sae proposed asking for help from her estranged, wealthy father-in-law who owned land. Although Hiroki had left home because he disliked his greedy father, he reluctantly went to the family home with Sae. The father-in-law, Katsuharu, agreed to provide financial assistance, but behind it was a sinister plan... 'The collateral for my husband's debt is my body.' The inhuman father-in-law raped the daughter-in-law.
