The video shows who appears to be Jang Moon Bok drawing on a piece of paper with the writing "Do you want to walk together? 2017.7.20." Along with the sketch, a teaser of what the music will sound like can be heard. Despite the video being only 15-seconds long, the calm melody of the guitar fits very well with his voice. From the snippet, it is possible to assume he will be rapping on this soundtrack and perhaps show the audience how much he has improved.
Stay tuned for his music release!
