@KeiriQ well like usually the "villainess" would be the one to face the bad endings (aka death, etc.) and is also usually is higher in class or position, often in the role of the queen or being engaged to the crown prince or something of that nature. The heroine is usually the opposition to the villainess that ends up pulling mostly good endings which often have something to do with good-looking dudes which all follow a trope of some sort, basically a reverse-harem. Arisa obviously didn't die and Scarlett does die so Scarlett would be a villainess in a story in which heroine and villainess roles were relevant, but I very much agree with you that I doesn't make much sense in this context based on what we have seen so far. From what I've seen, although Scarlett does seem more like a heroine, it's only possible to view her this way because the reader knows that she didn't purposefully do bad things but those bad things were blamed on her instead. From the view of the people that were led on by Arisa, Scarlett very much could've looked like a villainess.
