How to evaluate the friendship between Zray and Andy?

I think you know Zray and Andy because of the TV series Family with Children. They play brothers and sisters in it and often bicker, but they are classmates in private. They go to a school in junior high school, so they have a good relationship. Then they were lucky to be in the same class when they were in college, so they grew up with each other, which was considered childhood friends, so they had a good relationship. Andy once said in the program that she forgot that Zray was a man and Zray forgot that she was a woman, so for them, the relationship between the two people was too close and there was no gender boundary. I think the friendship between them is enviable, because it is rare to have such a friend by my side. I remember once attending an activity, Andy's skirt was too big, so it was inconvenient to walk and turn around, and Zray silently helped her untie the skirt behind her back, which made me feel very warm. Although we always bicker at ordinary times, we still choose to help each other at the critical moment. I think a friendship like theirs will not deteriorate even if they don't contact for a long time, because their feelings are already deep and can't be destroyed so easily. There are also many netizens who think they should be together, but I think they have known each other for so many years. If they had such feelings, they should have been together long ago. Since they didn't choose to be together, it seems that they have no such feelings for each other, only friendship. Andy wants to test the role of boys in his life when he plays fortune-telling games on the show. His first test was Zray, which shows that Zray must be very important in his heart. Everyone is very funny to see them together. They are rude to each other and often have some disputes, but they still care about each other and rush to each other when they need help.
