In the fifth year of their marriage, Isaac Pinecroft hired a young secretary for Reina Morley. "Nina Irwin is my friend's daughter. She's young and a little hot tempered. Be patient with her and teach her slowly." When they first met, Reina had no idea that this girl would one day become a serious threat to her. It was not until three months after Nina joined the company that Reina saw that scene from the floor to ceiling window on the second floor. With her own eyes, she saw Nina tangled up with a man, pulling and struggling with him. That man was none other than Isaac, the husband she had been married to for five years. Reina waited for him downstairs, wanting him to give her a clear explanation. But he only said carelessly, "I'm just playing around with her. She insists on calling herself my mistress. How about this, we get divorced first. After three months, when I'm done having fun, we'll remarry." "Okay." Reina agreed without the slightest hesitation. 'But Isaac, there will never be any remarriage in my life. Since you choose someone else, then I'll grant your wish!'
