One common element is family. In Tamil love stories, family often plays a crucial role, either in supporting or initially opposing the relationship. Another is the cultural backdrop. Tamil traditions, festivals, and language often form an important part of the story. For example, the couple might meet during a Pongal celebration. Also, the concept of loyalty is common. The lovers stay true to each other through various difficulties.

Despite facing some minor differences in their caste backgrounds, they fought for their love. Eventually, they convinced their families and are now a happily married couple.
