I'm not sure who Kartik and Naira specifically are in this context. There could be many couples with those names. Maybe they are characters from a local story or a show in a particular region. Without more information, it's hard to tell their love story.
Kartik and Naira's love story, since we don't have much background, could be like many other love stories. It might start with a chance encounter. They could have met at a social event or in a place where they both had a common interest. As they interacted more, they discovered shared values and dreams. Maybe they had to overcome family differences or personal insecurities to be together. But again, this is all just a general idea as we don't really know who these Kartik and Naira are.
