Girl group SECRET's member Hyosung revealed a professional attitude despite her bad physical condition.

In MBC Music "Show! Champion" aired yesterday, Hyosung came out and performed her song "Good Night Kiss" live perfectly even though she is not in a good condition.

Hyosung also posted on her SNS before the live show, "Be careful of the rainy road. Preparing for 'Show Champion' right ow. See you later, be careful not to get sick" in a 15-second video.

One representative from TS Entertainment said, "Hyosung has been called everywhere from radio to music programs and even dramas. We tried to minimize it as much as possible but she's been handling so many that she was diagnosed with an infection in her throat. To be honest, singing live is impossible right now."
