This is usually what happens if the company decides to ignore the rumours and just push through with their plans. Helps for now but could backfire badly if the rumours start to pop up again later and maybe even turn out to be true.
Basically the group could always self destruct at this point. This is not the same as Soojin and Cube. Soojin's actions weren't known before her debut with Gidle. You can't blame Cube or the group for her debut. Hybe knew about the rumours and willingly decided to continue with Garam.
Also keep mentioning the garam rumours under the teasers for the other members is unfair to them. They worked hard to get their and shouldn't get blamed for the possible actions of someone else.
