Boom's comeback on SBS's "Strong Heart" significantly helped the show.
The episode of "Strong Heart" that aired on September 6 starred Boom who finally came back after serving the military for two years. On the show, Boom revealed his latest song, "Boom's Back," along with his new dance called, "Boom Kwang Dance." With these new features, Boom didn't look like the military affected him in a negative way. Instead, it appeared like his two years of experience with the military really helped him become an upgraded Boom.
