Because of her combat prowess, Natasha Veronica Martinez is referred to as a mystery lady. Her organizers dubbed her a "phantom" in the morning and a basic architect in the evening. She makes a mistake because when she returns, the man she once loved is chasing her. The man had once captivated her heart during their eight-year relationship, but she promised herself that she would never again affect anyone, not even the man she once loved. But she did not expect the wind to change; the promise she had made to herself was gradually broken, and in their union, she proved even more that she could not bear to see the man she loved hurt. Can she forgive? Or will her desire to stay away from those who have ruined her life remain lofty?
