Bound To Love You Domineering CEO

She was forced to accept a marriage proposal from a strange billionaire to pay her huge debt and to take back her inheritance left to him when her mother died. 
Nathan’s lawyer handed her the documents, including the marriage certificate. 
Things were moving much faster than she had imagined they would, and everything happening seemed too easy. Too good to be true - a voice in her mind cried out - Be careful! It’s a trap! If it was a trap, though, it was very cleverly hidden.
Crystal contemplated the proposal for a moment before addressing Mike, his lawyer. “I only have two questions,” she said. “The first question is this: if I sign it, does it mean that I don’t need to pay my debt?”
Mike: “Yes. And your second question...?” 
Crystal: “Okay, I haven’t reached the legal age for marriage yet, so even if I sign it, it won’t take effect. Is that right?”
Nathan quickly raised his hand and said, “If I say that it is effective, no one will dare to say that it isn’t. Do you believe that?”
“I suppose so,” Crystal admitted. She hesitated for a moment, and then she signed the marriage certificate. 
Months later, she asked for a divorce from him. He stared at her in silence, then he uttered, “Have I ever told you how much I love you?” 
“What does that have to do with our divorce?” Crystal asked.
“I’m only asking because I care about you,” Nathan murmured.
Suddenly, tears began to stream down Nathan’s face. 
“I’ll be happy if you say that you care about me,” Nathan continued. “Why must you torture me this way? Haven’t I done enough to prove my love for you?”
She was stunned hearing his confession and words stuck on her throat. 
Nathan carried on with his little speech. He said, “I have died once, and the fear of death has no hold on me. But if you admit that you care for me, then I will live for you! So, please, love me once, and I will be at your disposal!”
