In a billion$ of $tar

My name is Joshua, I used to be a simple man living in my own small world with my foster parents but that world collapsed when I found out my true parentage, the only child of a very famous and rich business. In time I found out that my real parents were murdered by those that claim to be the 3 most powerful and forbidden families in the country and from then, I knew I had to change to avenge my real parents and I became the perfect unfeeling CEO in my parents company dedicating the rest of my life to growing the company and getting revenge on the 3 forbidden families
