Girl group Girl's Day's member Hyeri calmed her fans down by saying that she is okay.

On January 16, Hyeri posted on her Twitter, "Sorry for bringing you worries. I'm fine! Thank you so much for worrying for me! See you tomorrow bright and healthy. Everyone, be careful not to get sick... cough cough.."

Internet users who saw this commented, "Take care," "I was so scared," etc.

Hyeri had come out on Mnet "M! Countdown" to perform "Something" with her group, but right after her stage, she fainted on stage. One representative said, "Hyeri had been suffering from a cold since a few days ago and her body finally gave up."
