When it comes to romantic stories, the characters are often referred to as the "romantic leads". However, there are several synonyms that can be used to describe these key characters. They can be referred to as the "lovers", "sweethearts", "paramours", "affectionate pair", "courtly couple", "amorous duo", or "passionate partners". Each of these terms brings a slightly different connotation to the relationship between the characters. "Lovers" and "sweethearts" suggest a younger, more innocent love, while "paramours" is a more mature term for a secret or illicit love affair. "Courtly couple" and "amorous duo" bring a touch of sophistication to the romance, while "passionate partners" emphasizes the intensity of their connection.
