He apparently prepared for these scenes by taking lessons for two months from a professional ice hockey player, demonstrating his dedication to his acting.
The drama's staff stated, "Seo In Guk normally likes sports and because of his athleticism, there was no major difficulty during filming. But due to filming for two days straight in a heavy hockey uniform, it must have been very hard stamina-wise for him. He still kept up an energetic atmosphere with his vigor that is characteristic of a high school student, making a satisfying cut."
As mentioned previously, Seo In Guk plays the lead role of Lee Min Suk who lives a double life as a high school student and company director at just 18 years of age. 'High School King' is set to premiere following 'Witch's Romance' on June 16 at 11 PM KST!
