What kind of two people will become good friends?

I think that in order to maintain a friendship between men and women, at least one of the following conditions must be met.

1. Both men and women have their own lovers, and they are all true love, and their feelings are very stable and strong.

2. The other party has shortcomings that he can't tolerate. For example, a pair of boys and girls who are friends, they play together because of the same interests, such as playing games or photography, so they often communicate together and are in tune in this respect. But at the same time, this girl may not agree with this boy's personality, thinking that he has no ambition and only knows how to play all day. Moreover, this boy may think that this girl is particularly gold-worshipping or something, or she is too ugly. These shortcomings do not affect two people to become friends, but if they want to become lovers further, both men and women find it difficult to accept. After all, the requirements between lovers are much higher than those between friends.

Both families are familiar. For example, the father of the man is the brother of the wife of the brother of the woman's father. The two are not related by blood, but they are also relatives, so they have often met since childhood and called each other brother and sister, and they are not familiar with each other. Legally, you can get married, but you feel emotionally and psychologically connected, so you can't develop anything except friendship.

If both men and women admire each other very much and think that the other is not only excellent, but also to their liking, then in my opinion, it is unlikely that they will become pure friends. Maybe it will develop into a confidante/confidant, and both sides secretly like to make a little ambiguity occasionally to adjust their lives.
