Billionaire Great Temptation

She lived a perfect life during her younger days, full of love and happiness, but it shattered when her father and step-mom died together. She survives with his step-brother, but life becomes challenging as the latter falls into a severe mental illness. Her young mind aims to save him, and the opportunity had come; someone offered her to be a surrogate mother, but the man she'll going to sleep with was the same person she fell in love with the moment she first laid her eyes on him a few years back. She accepted the bargain in exchange for a vast amount, despite her hesitation and fear. He hated her and accused her of being a user after that night. Leaving with no other option, she accepted all the humiliation and insults coming from him. After giving birth to her child, she painfully witnessed it was taken away from her.

Will they live a happy life when he wanted to hurt her? How would they tell their daughter the painful truth about her sudden birth?
