Recently, Se7en made his first radio show appearance since his comeback as he made an appearance on August 19th's radio broadcast of SBS Choi Hwa Jung's Power Time. In his visit, Se7en had a special mission. The mission was that if there were more than seven thousand supportive messages posted on the radio show's board, he had to show his tattoo. Later on, it was revealed that he had around eight thousand messages, so he revealed his tattoo that was drawn on his upper left arm. As seen in the photo above, the tattoo reveals a drawing of a treble cliff that has a wing attached at the front, and behind it is what looks like a sun. Regarding what the tattoo represents, he commented, "It expresses my desire to commit myself with music and to fly high with my goals I have set." Fans and netizens who have seen Se7en's tattoo have replied back things such as, "Oppa~ I am satisfied that you showed your tattoo through this mission," "The tattoo looks more upgraded than before! Very cool!," "Forget about the tattoo, I am happy to see your muscular arms" and "I am impressed with the eight thousand messages. Must be the Se7en effect!"
