Sunny, the background of Li Shungui's growth.

Sunny was born in the United States on May 1989 and moved to Kuwait. Later, due to the Gulf War, her family moved back to South Korea. Judging from her childhood memories of the war, she is still a little afraid of fireworks and sudden loud noises. There are two sisters at home. As the youngest daughter, she is very coquettish (but not intentionally, that's the way she usually gets along with her family. She doesn't think it's coquetry. After nine years of training in the economic company run by her father, when she was about to debut, the company was about to close down. Later, Senior Ayumi thought her qualifications were good, so she was recommended to participate in the interview of S.M. Company. After selection, she qualified to enter S.M. Company as an intern. It happened that the company was planning the debut of a large women's group and was selected. Sunny's father and Li Xiuman, the president of S.M., are brothers, but their relationship is not good, and they didn't give Sunny more resources because of their relatives, so she can't get where she is today without her constant efforts.
