   Summary

   "Nothing could break Kalego. At least, that’s what he’d insisted had been the truth for years. He was raised by a mother and father that carried business and outward appearance more important than anything else. His older brother, whom of which he simultaneously has not seen in years and knows is one of the richest men in the country, was a stunning for example for Kalego growing up. He’d worked hard for the thirty-eight years of his life he’s been alive. He’d fought tooth and nail to get to where he is today.

   Yes, of course, Kalego was a strong man whose composure and morals could not be broken.

   And then along came Opera."

    

   Or, Kalego and Opera let go of their inhibitions.
