Would you rather drop a failing group for a successful solo member career or keep a middling group with hopes that it will one day escape nugudom?
Scenario 1
Failing group, but you do have a famous member, think pre-bully days Naeun April, would you rather drop the group for that one successful member's career, let their wings fly. You cut the losses, since investment into the group would just go down the drain. Or would you rather;
Scenario 2
Keep the group and even if it doesn't work, keep going at it. Maybe one day you can get a music show win, other members may gain popularity. Think Astro with Eunwoo.
