He continued, "I hadn't initially planned for the promise to be about rap, but because of Yesung, I decided it would be. Back when I was a part of 'TJ Project', there was a 'TJ Girl'. This time, I plan to do it together with Yesung and Baek Sung Hyun, with the concept of 'TJ Boy'."

The 'TJ Project' was a brief project during which Jang Hyuk participated in a rap release. When asked about it, he simply said, "I did not promote as TJ because actor Jang Hyuk wanted to become a rapper... It was a time when actors could shape their images through MVs. TJ was also with the purpose of shaping my image through a brief but memorable promotion."
