Singer IU is worrying her fans after she revealed her dark circles.

On April 2, the singer shared two selca pictures on her fan café with the title: “I am in Japan!”

She also captioned: “I feel like I can fall asleep within ten seconds if I close my eyes because of the medicine I took for my flu. Currently waiting for my turn on stage.”

In the shared selca pictures, IU looks pallid with her pale face and black ribbon on her hair. The dark circles seem to stand out on her face.

IU also worried her fans last month with a similar picture showing dark circles yet again.

Fans and netizens who came across the selca pictures commented: “Murderous schedule?”, “This is going to hurt her skin,” and “Take care of yourself.”
