A yandere girl in manhwa is often extremely possessive and obsessive about the person she likes. She can go to extreme lengths to keep them close, sometimes even resorting to violence or manipulation.
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.
