Of course, with the news, fans relayed their concern about the vocalist's health, so she has taken to Instagram to reassure them all personally.
She wrote, "Everyone!! You were really worried, right? I'm going to take medication and get better quickly, so do not worry too much. Everyone seems so shocked that I feel sorry for troubling you... It is such a shame that I can't stand on stage for the end of the year. Please give lots of support to the members' cool stage!!! I will quickly get better to show all of you my healthy image. Sorry for worrying you. Thank you and I love you!!!"
Get better soon!
