In romance novels, first base, second base, and third base usually referred to the three positions on the softball field. First base is the first base that faces up, second base is the second base that faces up, and third base is the third base that faces up. In novels, these positions were often used to describe the places or scenes where the characters were located and to hint at the relationships between the characters. There was usually a "home plate" between first base and second base, which was the home plate where the character was. In the home plate, the character can attack the opponent at will, but if the opponent hits the home plate, the character will be directly eliminated. In third base, the character could not attack the opponent, but if the opponent hit the third base, the character would be directly eliminated. In novels, these positions and scenes were often used to describe the relationship between characters, emotional entanglements, and the results of competitions. At the same time, they could also convey the author's feelings and thoughts through the characters 'actions and words.
