I'm not entirely sure as I haven't read it specifically. But generally, a 'villainess' light novel might be about a female character who is initially seen as a villain in a story, perhaps in a fantasy or fictional setting.
The protagonist who is reincarnated as the villainess is very important. Also, the prince is a significant character as he is one of the main love interests in the story. Then there's the heroine of the original game who also plays a role in how the story unfolds.
In 'My Next Life as a Villianess Light Novel', the key plot point is the reincarnation of the lead character into the role of the villainess. She uses her knowledge of the game to rewrite her fate. She befriends characters that were supposed to be her enemies in the original game plot. Her attempts to change the story lead to various comical and heartwarming situations. She also tries to find her own path in this new world, rather than following the doomed path of the villainess.
It forces the villainess to either accept her fate or strive for change. If she accepts, her character may show resignation and a sense of hopelessness. If she tries to change, it can lead to a more complex and evolving character.
Well, in the context of the villainess novel, it's quite a staple. The idea that 'death is the only endig for the villianess' often plays into the moral framework of the story. These novels usually have a protagonist who is trying to avoid the fate of the original villainess. So this statement is like a dark cloud hanging over the character, making the reader more invested in whether she can change her destiny or not. It also adds to the drama and tension in the plot.
