Hao Ren was born in another world and has lived for over twenty-two years being nothing but a definition of the word, average. After a high school reunion, the young man sat down on the beach shore, and mumbled to the sky, “God of Novels, you are unfair. I spent forty years of my life doing nothing but reading books and stories written by others. I worked hard to manifest this rebirth, and yet you did not bless me with anything. Why?”A voice echoed in his mind, “Host, you have the Omnipotent Husband System.”Hao Ren scoffed and scolded the system, “What is the use of having you when you are not even active? Are you shitting with me, you bastard?!”The system replied, “Host the condition for activating the system is to get married.”Hao Ren could not handle it anymore and cried out loud as he complained about this condition. He was not good-looking, and neither was he wealthy, who was going to marry him?Tired, he spent the on the beach. When he was returning home, he passed by the marriage registering center. He sighed for his fate but suddenly, a beautiful lady asked him, “Hey, do you have any identity card on you?”Hao Ren nodded in a daze, and the lady dragged him inside the office. The young man was yet to register what happened to him when an automated voice sounded, “Host, congratulations on getting married. Omnipotent Husband System is now activated.”...Years later, Hao Ren became an entity many people wished to meet. However, Hao Ren never stayed outside, to everything he had one reply, “I have to go home and cook for my wife.”Would you like to know his journey from an average to an over-achieving person standing at the apex of power and prestige?

“Let me tell you something honey, Revenge is the best dish served cold.’’****To her, betrayal was the most excruciating pain in the world—the kind that pierced her soul.The people she had loved with her entire heart had not only failed her, but ruthlessly deceived her.“How could you?” she had once cried, her voice shaking as she stared at the man she had chased like a madwoman. But he had already cheated on her—expecting a child with the very woman she despised with every fiber of her being.Her so-called “family ” was no better. The relatives she thought she could trust? They only wanted the inheritance meant for her and her little brother.The people who once smiled sweetly and flattered her? They were nowhere to be found when her glamorous and envious life crumbled to nothing.“I thought you all cared about me...” she whispered bitterly, watching as one by one, they all turned their backs on her when she needed them the most.In that devastating moment, everything became painfully clear. The bubble she had lived in popped and she finally saw their true faces.But....it was too late.Everything she had was gone, slipping through her fingers like sand in the wind.Except for him.Her former fiancé, the one man she had tried to ruin with every scheme she had planned, remained by her side until the end. He stood by her, even as she took her final breath.She had accepted her tragic fate—until something phenomenal happened. She woke up once again.Back to the past.Where nothing had happened yet.
