Hyorin appeared on KBS 2TV's 'Global Request Show' and gave her honest opinions about malicious comments and criticisms.

The singer revealed that she often checked comments left on the internet in order to see her fans' thoughts and responses. She said, "There turned out to be a lot of criticisms... Once in a while, I would get really angry because of malicious comments and even wanted to know who wrote those words."

She continued, "The person who wrote the comments may have done so easily, but those comments could really hurt someone and even cause someone to have plastic surgery."
