SM Entertainment has already responded to the situation, but it seems Taeyeon wanted to reassure fans she was doing okay. On August 18, Taeyeon made the post below with the message, "I'm fine. I'm finished with the performance. It's the end of a scheduled day."
She added, "Thank you for cheering me on and holding up pink lights. This situation was my agency's mistake, so don't feel too bad about it."
