Ga In was scheduled to attend a university festival on May 24th, but Mystic Entertainment took to her official fancafe to post the following notice:

"Hello, this is Mystic Entertainment. 

Ga In will be unable to attend the festival at Sang Ji University in Wonju scheduled for May 24, 2017 due to health related issues. 

After a series of abrupt cancellations with her previous scheduled festivals, Ga In wanted to repay fans with a good performance this time, but after being advised from the hospital, she will be hospitalized in order to receive treatment and take rest. 

We once again deliver apologies to fans who were waiting for Ga In, and will notify you of any further developments in the future. 

We hope fans will understand." 

The label has not specified any tangible reasons for Ga In's health issues. Still, get well soon, Ga In!
