A qualified female supporting role must remain unmoving in the first half of the plot, waiting for the relationship between the male and female protagonists to develop; come out to disrupt the situation in the middle of the plot, and use skills to heat up the relationship between the male and female protagonists in the chaos; and more importantly, turn into a vicious female supporting role in the later stages of the plot, committing suicide and bringing the male and female protagonists' relationship to its peak.
