Can sibling love really work?

Of course. True love can transcend time, space and all ages. In fact, as long as men and women are affectionate, age can be ignored. Just like French President Macron and his wife, who is many years older than him and is a teacher in Macron, they have a very good relationship and are true love. Sister-in-law's love is possible, depending on the degree of relationship between two people and their concern for each other. Deep affection will never be forgotten since ancient times. I believe that true feelings exist, thank you.
