Xing'er and IU have attracted public attention and love since their debut as a duo of S&U. Unlike IU, who is known as the nation's younger sister, Xing'er has always maintained a mysterious image in the entertainment industry. She does not appear in variety shows or act, and only devotes herself to writing songs and singing. If you ask her why, she will look at you lazily and say, "Don't you have Zhi En Oni?"
Even though there are very few opportunities to get to know her, she still has a circle of fans because of her creative genius and perfect appearance. This time she was tricked by the president into being a mentor for the second season of Produce101. Although she was always reluctant at first, but after getting in touch with her, she found that this was a group of cute teenagers who worked hard to pursue their dreams. During the time with them, she also gained the most precious thing. . .
