The hero and villain in manhwa are usually presented in a way that contrasts sharply. Heroes are often idealized, while villains can be quite sinister and manipulative. However, there are exceptions where the lines between good and evil are blurred.
A true villain in manhwa is usually someone with a deeply selfish and malevolent nature. They often have no redeeming qualities and are driven by pure evil intentions.
The villain with a crush might show conflicting emotions. They could be cruel in their usual actions but soft and vulnerable when it comes to the person they have a crush on.
