Recently, SNSD participated in the show "Knowing Bros" as a guest to promote their 15th debut anniversary album. In the part of sharing each member's keywords, Hyoyeon said "I believe that basic human nature is evil".
When asked why, Hyoyeon shared about the malicious comments she has faced during her 15-year career:
"I started thinking like that when I was active in music. In the past I never cared about malicious comments and always kept a positive attitude. But they didn't know anything about me and kept writing things maliciously based on false rumors or body-shaming. They don't even think about how others feel when they write them. How can't I angry when read those comments?
They should come and see me face-to-face. If I don't have a schedule, I really want to meet all of them and tell them to tell me straight."
When asked if she would respond to those comments, Hyoyeon bluntly replied, "They're not worth it for me. But when you think about how we were born knowing nothing about the world and starting to learn everything, I think human nature is inherently evil."
