I still don’t understand the singer purpose? How did her singing ‘ruin’ the fl fami...

So basically from what i understood is that , the singer is singing songs around their land in which contains lyrics of our FL family ( thr lyrics didn’t exactly mention our FL family name but basically a few part of the lyrics describe characteristic of our FL family ) in which then indirectly spreading bad rumours in order to tarnish the FL family reputation so her dad wont get the one of the high royal court position

The bad guy basically use singer to spread rumours to ruin FL family
