In the play, Mary and Cheng Jinyun are girls with different personalities. One is as fierce as a red rose and the other is as holy as a lily. They appeared in Mingtai's life one after another.
If we want to talk about love, I think Ming Tai Yu Manli is out of curiosity. For Cheng Jinyun, he is a soul mate. Therefore, Ming Tai fell in love with Cheng Jinyun when he matured.
As a female perspective, Mary's role is actually more diverse and hierarchical. After many hardships, she became a spy and finally became a life-and-death partner with Ming Tai. Mary is like a black swamp, and the story behind it is shocking and sad.
Extended data:
Cheng Jinyun is a perfect and mature new woman. She has a clear-cut belief guidance and spiritual companionship for Mingtai. Unlike Yu Manli, she put her whole heart on Ming Tai, but made her feel her charm and independence. Cheng Jinyun's appearance gave Mingtai psychological comfort. After performing the task, she can talk to Cheng Jinyun painfully.
At that time, the lost lamb Mingtai happened to meet Cheng Jinyun who braved the holy light and was fascinated by her personal charm. She was deeply immersed in it and couldn't wait to give a kiss.
