GFRIEND's Umji is taking a break from music to concentrate on her health Facebook/Umji-G-Friend

G-Friend's Umji will not been seen with the girl group for sometime. The band's agency revealed that the 25-year-old singer will be taking a break from the activities due to her heatlh.

The statement read: "Hello, this is Source Music. Umji recently felt some pain in her leg, and after receiving the results of her examination it was found that her sartorius muscle has been strained. The sartorius is a long, thin muscle that is used when walking or using one's knees, but because it is strained it is causing pain."

"Following the doctor's advice that both rest and treatment are needed for recovery, Source Music is placing Umji's health as a first priority and focusing on her treatment. Until Umji heals, GFRIEND will be promoting as a five member group with Sowon, Yerin, Eunha, Yuju, and SinB," the announcement stated.

Earlier this year, netizens suspected that the hateful comments are affecting Umji's self esteem. During a performance, she was seen covering her face with her hair, and head tilted down to avoid looking at the crowd.
