I saw this on weibo, it looks like an official TA message
The unexpected hit song Who... was featured in a CDTV show! Those TA members who took a dislike to ayu, please don't forget the time and youth you spent with ayu; even if you decided to leave TA, please don't forget that ayu's songs will always be by your side. I pray that this singing voice will reach you... (The last sentence is from Who...)
Translated by me
Now I'm worried about again and future releases...
