4minute's HyunA has said that "life is hard" because of her struggles during the shooting of her Change MV. Through the recent episode of SBS Strong Heart, HyunA explained the reasoning behind why she shouted out her frustration in anger. During the show, HyunA explained, "At the time of the shooting [Change], it was around 11 degrees celsius, and I had to film the MV while getting hit with cold water...I usually don't think of hip shaking 100 times and not being able to see my parents as all that hard [in life], but at that time, I just couldn't hold it. So I shouted out 'Life is hard.'" HyunA had to film in adverse conditions, as the filming was set outdoors during the middle of the winter, and cold water was sprayed on her for the MV. After explaining, HyunA also added, "I get a bit rude when I get angry."
