Although the imperial concubine in the palace is heartless to Hua Fei, what details show that he is affectionate to this woman?

I have seen this queen in the palace for nearly fourteen times. I'm still watching it for the fourteenth time. To tell you the truth, I have watched it so many times. I really didn't see from the details you said that the emperor had feelings for Hua Fei. I really didn't see that he loved Huafei. I can only say that Hua Fei was just a way to praise Nian Gengyao. He doesn't love Hua Fei, but he loves Hua Fei.

First of all, Hua Fei was doomed to tragedy from the moment she entered the government. Before the emperor became emperor, he had a plan. He reused Nian Gengyao, but in the long run, he was afraid that if one day the minister was cornered, so when he reused Nian Gengyao, he took his sister as a concubine to show his attention to Nianjia, but he also knew that Huafei could never be pregnant with a child, and Huafei could never be allowed.

So when the emperor was just a brother, Hua Fei was pregnant, and she was pregnant for four months. At this time, it was the emperor who designed Duan Fei to take the bowl of safflower to Hua Fei, and Hua Fei had the best relationship with Duan Fei at that time. She believed Duan Fei, so she drank this bowl of safflower, which is said to be an anti-abortion drug. In the end, the child was hopeless. It was a male fetus, designed by the emperor and the queen mother.

Even when the emperor is not an emperor, he is so cruel. He is too afraid that someone can threaten his position. That's why he used a special fragrance for Hua Fei alone in the future, and this fragrance contains musk, which will make women infertile after a long time. He doesn't want this woman to be pregnant with his child. He clearly knew that this woman wanted a child of her own, even a princess, but he didn't leave any way out for this woman.

Every time Hua Fei restores her favor, it is not because the young and middle-aged have won the battle again and made contributions to the court, so Hua Fei will always be in favor, but also because her brother is too powerful, which leads to her falling out of favor so quickly. After all, the emperor is suspicious.
