Losing a member is a bigger damage than having a member caught up in scandal. Le Sserafim had slightly higher chance of hitting big with Garam than without

member line up changes is what causes damage which means adding or subtracting. If le sessarfim was an established group i would agree that her removal would have a big affect but it happened so early and majority of the fandom had no problem turning against her.

At this point adding a new member would do more damage than garam leaving this will upset ot5 stans and garam stans.

They will probably do better now that Garam left.
