Wonder Girls revealed that it was Park Jin Young himself who asked them to write their own album.
On the August 13 broadcast of MBC FM4U‘s “Sunny’s FM Date,” Wonder Girls appeared as guests. On the broadcast, Sunny, the DJ, prompted the girls by saying, “You took part in the production of every song on your album.”
The Wonder Girls members said, “In the past, we teamed up with composers to write songs. But this time, Park Jin Young said, ‘You should try doing it all on your own this time.'”
They continued, “So we just did it on our own,” inciting laughter. In particular, the members said, “The youngest, Hyelim, burned it up with writing the lyrics.”
