In this chapter, we learn that the "secret weapon" of the butterfly concert is a young man named Lin hui yin, who is a member of the boy's band, the "t4." The "t4" is the male version of the "boy's" , and the female version is the "girl's." The t4's "talent" is better than the butterfly's, but the t4"s "audience" is "boring," and the "media" are "boring" . The butterfly, on the other hand, has sent its "ace singer" zhong "mingyu" as a guest for the concert. Although the "popularity" of zhong is higher than that of "the t4.," the "audience's development potential is "far less than" the "butterfly."
