Yoon Mi Rae placed close behind at second place, with a total brand value of 950,680. 

The director of Korea Institute of Corporate Reputation explained, "With more and more female rappers getting media exposure, people's consumption of female rappers' brands naturally increased. However, when looking at the breakdown of positive versus negative brand ratios, the negative values are much higher. Among the female rappers, Yoon Mi Rae and Tymee have the highest ratio of positive brand value."
