The typical wealthy girl in manhwa is likely to have a huge mansion, expensive cars, and a closet full of high-end fashion. She may struggle with finding true friendship or love because people might be interested in her wealth rather than her as a person.
Well, it's hard to say for sure. Sometimes a girl in a manhwa wants a loyal partner, sometimes she craves personal growth and independence. Or perhaps she just longs for some peace and happiness in a chaotic world.
A naughty girl manhwa is appealing because it breaks the mold. The girl's mischievousness brings a lot of fun and surprises. Also, the story might explore themes that are not common in other types of manhwa, making it stand out.
It's a story that probably involves the adventures and interactions of a not-so-smart guy and a girl. But I haven't read it myself, so can't say for sure.
Since we don't have much information about the 'girl in body cast story', it's impossible to know who the girl is. She could be anyone - a girl from a small town, a student, or an athlete.
It might include scenes that establish the theme and tone of the entire manhwa. Perhaps it gives a glimpse into the girl's desires or aspirations that drive the plot forward.
