One netizen, who claimed to be a great fan of B2ST, shared thoughts on an online community, writing, "If you were going to leave, you should've left quickly. Why didn't you leave the past 8 years? B2ST is a well-known popular group. I can't even imagine how greatly this is going to affect them... So f***ing annoyed. You are a burden. When you got eliminated from Big Bang, Yoseob brought you to Cube Entertainment, and you were able to debut. Then you should have lived thanking Yoseob for the rest of your life. You crazy f***."

Other B2ST fans showed strong agreement as they commented, "Don't you dare mention B2ST's name from now on. Don't be selling their name for your benefit. Also, don't think that Beauty will cheer you on. Live happily with your party buddies. Thanks for leaving B2ST. It would've been better if you left earlier," "I was a fan from debut, but whatever, live happily.. I used to love you such much you b**** ," "You are now going to suffer and realize how greatly B2ST affected the degree of your popularity," etc.
