Woollim Entertainment stated on the 12th, "Although it is Lovelyz' debut day, unfortunately only 7 will be going on stage. We've decided that the first priority is getting mental help for Seo Ji Soo. Until she has received treatment and we have caught the perpetrator who has brought about this issue, Seo Ji Soo will not be joining promotions. However, she is not leaving the group. This is just a halt to her activities."

"Seo Ji Soo has been swept up in absurd rumors and is having a very difficult time. She is unable to regain stability nor go on stage. Thus, this morning she headed to the hospital."

The rest of Lovelyz will hold their debut showcase as scheduled today. Since there has so far been no announcement of any changes in the girl group's upcoming release or schedules, it's expected that everything will go on as planned while Seo Ji Soo focuses on dealing with the rumor and getting mental help before rejoining the team.
