What does the so-called "lover" mean on Valentine's Day?

Valentine's day lovers refer to lovers who are in love but not married, not extramarital lovers. From the legend about the origin of Valentine's Day, it can be proved that:

First, in the 3rd century, there was a full-scale crisis in the Roman Empire, and people rebelled. The aristocratic class carried out cruel repression. One of them, Valentine, was arrested and imprisoned. In prison, he and the warden's daughter love each other and are taken care of by the warden's daughter. On February 14, AD 270, he was sentenced to death. Before the execution, he wrote a long suicide note to the warden's daughter, saying that he was innocent and deeply attached to the warden's daughter.

Later, in order to commemorate Valentine's sacrifice for justice and pure love, Christians designated this day as "Saint Valentine's Day" and later generations changed it to "Valentine's Day".

Second, in the 3rd century AD, Emperor Claudius II of the Roman Empire announced in the capital Rome that he would give up all marriage promises so that men could go to war. But a priest named Valentin went against this wish and continued to hold church weddings for young people who loved each other. After this incident was reported, Father Valentin was first flogged, then stoned to death, and finally hanged on February 14, AD 270. 14 century later, people began to commemorate this day. Chinese translation is "Valentine's Day", which is called Valentine's Day in western countries to commemorate the priest who died for his lover.

Thirdly, in ancient Rome, February 14 was a festival to show respect for Jonah. Jonah was the queen of the Roman gods, and the Romans regarded her as the goddess of women and marriage. The following February 15 was called "Lupsala Festival" to show respect for other gods under Jonah.

At that time, the lives of boys and girls were strictly separated. But on Lupsala Festival, boys can dance with girls of their choice. If girls are interested in boys, they can always fix them up and eventually fall in love and get married in church. For this reason, future generations designated February 14 every year as Valentine's Day.

Fourthly, it is said that in Britain, all birds used to mate in February 14, such as blackbirds and partridges, and they all courted in February. Therefore, human beings also think that February 14 is a good day for all things to spring, which represents the beginning of youthful life, and also follows the example of birds in choosing partners on February 14 every year.

Judging from the above legends, the establishment of Valentine's Day has something to do with the mate selection of men and women, and has nothing to do with extramarital affairs.
