Valentine's Day, also known as Valentine's Day, is a national festival in some countries in Europe, America and Oceania. This festival has many origins, but it is generally more common after the execution of Valentine, a Roman saint, and later designated as "Valentine's Day."

In the third century AD, the Roman Empire experienced a total crisis, the economy was in decline, the ruling class was corrupt, the society was in turmoil, and the people rebelled. In order to maintain its rule, the aristocracy brutally suppressed the people and Christians. At one time, a Christian, Valentine, was arrested and imprisoned. In prison, he moved the warden's daughter with his honesty. They loved each other and were cared for by the warden's daughter. The ruling class ordered him to be executed. Before his execution, he wrote a long suicide note to the warden's daughter, expressing his innocence. It shows his open heart and deep love for the warden's daughter.

On February 14, 270 AD ({sys:(year(now)-270)}), he was executed. Later, in order to commemorate Valentine's sacrifice of himself for justice and pure love, Christians designated this day of execution as "Valentine's Day", hoping that lovers would eventually get married.
