2. Japanese folklore: February 14 was originally the day when girls confessed to boys. Girls give lovers gifts to boys, but in the end it is no longer each other's business. It doesn't matter who offered to give gifts now. In Japan, if one party receives a lover's gift from the opposite sex on February 14, and has the same affection or affection for the other party, it will return the lover's gift to the other party on March 14, indicating that they are soul mates, so they designated March 14 as "White Festival".
