On the June 25th episode of 'Entertainment Relay', the show followed SISTAR at an amusement park, and a reporter asked Soyu if it was true her income is 1.3 billion Won (~$1 mllion USD) from her songs. She shook her hand and said, "No. Really, no."
Soyu said, "I saw that I was above Taeyeon sunbaenim. That's ridiculous. How could I make more money than Girls' Generation? People keep telling me to treat them to a meal, so I keep buying and buying but now I have nothing."
