Why Does Everyone Want to Be My Dad?

But before long, his mother's secretary came looking for him. "Young master, you're an adult now. It's about time you took over these businesses."

They were all after his mother's assets. One day, while chasing a white-haired boy, Chiya found another little white cat. The cat was tiny and adorable.
