Sojin and Hyemi have been friends long before Sojin joined Star Empire.
Sojin was a trainee under Big Hit before moving to Star Empire which is why she is close friends with BTS Namjoon and Hoseok. She even went to their concert to support them.
Sojin choreographs her own dances and writes her own raps. She admitted that it was very hard at the beginning, especially because she never rapped before joining 9Muses, but that she liked doing it and actively looks for inspiration in everyday life.
Sojin was part of a dance crew. The members include EXID´s Hyelin, B.A.P´s Zelo and BTS Hoseok and to this day they can be seen hanging out.
Sojin is famous for her clear and beautiful skin, which is why she was chosen as model for a makeup brand.
Sojin is very attentive. In most V-Lives she is seen to be the only member listening to the Leader while Gyeongree and Keumjo play around. She also has a good memory.
Sojin gets scared very easily, much to the amusement of fellow member Keumjo.
Sojin is one of the best idol dancers with a wide range of specialties like hip hop, modern dance, ballett, standard dance, latin dance, popping, idol dance and more!
