You typically can't kill the male lead in a manhwa. The story is built around them, and their presence drives the plot forward. Any attempt to do so would likely violate the established storyline and could lead to an unsatisfying or chaotic reading experience.
Typically, a female professor in manhwa is depicted as having a strong personality, being dedicated to her students' success, and facing various challenges in her academic career. Her appearance might vary, but her intellectual prowess and determination stand out.
Often, when the second male lead powers up, it adds a twist to the plot. It could lead to power struggles, new conflicts, or maybe even a shift in the readers' sympathies towards him.
Definitely not. Manhwa comes from Korea. It has unique features that set it apart from Chinese comic works in terms of art style, storylines, and cultural influences.
