SECRET's Ji Eun is in the midst of promotion for her solo track, "Going Crazy", but she's encountered a frustrating obstacle in the form of a severe cold. On March 18th, representatives of TS Entertainment warned, "Recently, Ji Eun went overseas with SECRET for another schedule in a country with a severe temperature difference. She caught a cold in the process. She's struggling with her condition right now." Consequently, Ji Eun was forced to lip-sync during her March 17th performance on Mnet's "M! Countdown". It's the first time she's ever had to lip-sync on a music program in her entire career. The representatives continued, "Due to her cold and condition, she had to lip-sync for the performance. She is receiving treatment at a hospital to quickly recover, so we will be trying our best to make sure that she can perform live soon."
