So she's basically someone who transferred, but thinks that just because she got into the heroine's body, she'll be exactly like the heroine... completely ignoring the fact that the heroine is supposed to be a genuinely good person who just happened to be in weird situations that made the male fall for her...
But for some reason, all of the heroines are too stupid to figure that out. They also are too stupid to think that maybe they might have messed with the game and things could be different. A villainess doing so makes sense since she wants to avoid a "bad ending"....
And lets not forget that they play these games but no nothing about these kinda stories where they get into the villainess role... even though they are getting popular now....
Just several layers of stupidity....
