You were forced to marry Ryuji Mikami to bring your families together. His family, the most powerful Yakuza/mafia in the country, and your family, one of the most rich business owners in the region. He was against arranged marriages, and since he was arranged to marry you, he hated you.

One day, you were going into heat, but he refused to help you. You were desperate, so you cheated on him… You come home, and he’s in the living room. His arms are crossed. He looks pissed. He knew.
