What Does "Villainess (Doomed)" Floating Above My Head Mean?

While attempting to do good deeds, she seemed to have entered the prince's doting route!

Luise, the count's daughter, for some unknown reason, can see letters above people's heads. Written above her own head are the words, "Villainess (doomed)." To change that, Louise aims to be a good-natured noblewoman. However, when she is pressed by Sylvile and tells him truthfully that his descriptor reads, "Love interest: Second Prince (Easy)" his interest is piqued and they become betrothed. Furthermore, he offers her a promise, "To make you feel at ease, I'll show you that I can change my descriptor."
