Legend of miyue: Why did the old wizard refuse to let King Yi Qu marry Mi Yue?

In the whole play, the most manly one is King Yi Qu. He is bohemian by nature, loves freedom, and doesn't like being bound. He could have been a handsome prodigal son, but he fell in love with Mi Yue, the concubine of the Queen of Qin. He was very affectionate to her and saved her in from the mire several times. However, for their combination,

Before the moon was born, it was predicted that it would dominate the world. Therefore, when she was still in the palace of Chu, some people tried to harm her, but they survived. Later, because she was a girl, those who had tried to harm her gradually let their guard down. She followed the princess of Chu to the state of Qin, and as a result, she was taken away by the king of Yi Qu before she stepped into the palace.

When she first arrived in a strange place, she was completely free from embarrassment and fear. She even saved a wolf child, who was later the famous god of war, Bai Qi. Such a courageous woman naturally made this overlord fall in love at first sight, so he moved the idea of keeping her. However, such a decision made Lao Wu extremely opposed it. The old wizard is not a simple man. Although the king is not him, he listens to him. The old man's wisdom is hard, but it's a pity that he has something to say, but he is still regarded as the god of Yi Qu. Because of this opposition and Qin king Palace's arrival to meet the moon, he had to let her go.

Later, when the King of Qin died and Qin Gong was in chaos, the two men came together again. This time, King Yi Qu said that he would marry her, and even almost died trying to save her. The old wizard was still very opposed, but at that time, the two had already liked each other, so the old wizard swallowed his anger and left, but it failed to stop all this.

Actually, the old witch's idea was right. Later, everyone knew that he helped her to become the Queen Mother. Two people had their own children, but they finally died in her court. It's really sad to think about it. I wonder if he regretted his decision before he died.
