I knew I shouldn't have any feelings for him, but the situation was too wild to ignore. When I received a wedding invitation, I was shocked to see that my ex was getting married. While I should have been upset, a part of me was tempted to attend the wedding. My friends encouraged me to enjoy myself, meet someone new, and lose my virginity. I had an incredible evening with a billionaire, and I couldn't stop smiling. However, there was a major issue. The billionaire wanted an heir, and it turns out he is my ex's future father-in-law!
