On January 15, the idol singer was spotted being assisted by her manager after returning from a performance in Malaysia.

A representative told DongA, "Solar sprained her back while practicing for her stage performance. She is planning to visit the hospital for a checkup in the afternoon."

Prior to this, MAMAMOO had performed at the 'K-WAVE MUSIC FESTIVAL' in Malaysia.

Seeing this, fans expressed great concern as numerous comments poured out via social media, even telling the star to not participate in MBC Lunar New Year special, 'Idol Star Athletics Championship'.
