Six years of marriage. All passion at night, but never tenderness in the daylight. Amelia Sinclair loved Christopher Zephyr deeply, and she swallowed the bitterness as if it were sweet. Her own daughter wasn't allowed to call him father, yet the son of his first love sat on his lap, learning to say the word "dad". The entire family treated that adopted boy as a precious heir, while her own flesh and blood was treated like a shameful stain. It wasn't until Amelia and her daughter paid with their lives—until Christopher signed the cremation papers with his own hand and then took the boy to attend his first love's welcome banquet—that Amelia finally understood. Love couldn't win love. A heartless man had no heart to give. When Amelia was reborn, she swore she would never again cling to that cold and humiliating marriage. In her past life, she had foolishly given up her studies, content to be a housewife and devote herself to her family. In this one, she submitted the divorce papers without hesitation, took her daughter far from the mire, and rebuilt her career until she stood at the top again. In the first week after Amelia left, Christopher dismissed it as one of her tantrums. By the first month, he brushed it off completely. It didn't matter to him what she did, so it was fine to let her go. Later on, he saw her again, standing tall among the industry's elite! Amelia was focused only on her career, and her daughter was focused only on finding herself a new father. And Christopher finally realized that they really didn't want him anymore. The man lost all reason. The one who had always been cold, proud, untouchable, suddenly threw away his dignity. He blocked the mother and daughter pair in full view of everyone, his voice breaking as he pleaded, "Honey, I'll kneel here if I have to. Please... just love me one more time."
