Singer Baekho and his "vocal master" Hwang Chi-yeul met after nine years and engaged in an epic muscle war. The video, released on the YouTube channel 'This Is Baekho' on the 20th, has become a hot topic, featuring Hwang Chi-yeul's harsh(?) past training methods that transformed 16-year-old Baekho into the "Waterbomb God" he is today, along with the beast-like muscular beauty of the two men.

As soon as Baekho saw Hwang Chi-yeul, he brought laughter by introducing him as "the person who has known me the longest among my guests" and "the only teacher who forced(?) me to exercise, saying that singing comes from physical strength." Nine years later, just as Master Hwang predicted, Baekho has become a representative muscle icon in Korea. Master Hwang also overwhelmed his student by showing off back muscles so defined it was hard to believe he is a balladeer.

In particular, the two engaged in a playful battle of nerves over workout methods, mentioning "old school" vs. "trendy routines." When Baekho provoked Hwang's inverted row method by calling it "a way people don't use these days," Hwang proved his authority as a master by successfully performing a one-handed pull-up. Baekho also showed off his massive back muscles, drawing high praise from Hwang, who said he looked like "a handsome man straight out of a comic book."

Hwang Chi-yeul's secret to maintaining a monster-like body despite being a "non-dieting" fan of rabokki and red pepper paste, along with the friendship of the two sweating together before Baekho's enlistment, provided great emotion and fun to fans. Fans reacted enthusiastically, saying, "Is it even legal for a balladeer to have muscles like that?" and "Both the master and the student have bodies that belong at Waterbomb."
