"She isn't the same hardworking person she was when she was on the show anymore."
There are hardly any performance stages in the country, and the company doesn't strictly require group members to practice every day either.
As such, even though there are professional dance and song coaches, everyone prefers to spend their energy on how to interact with fans and to increase their popularity.
Honestly, in this circle, wanting to be popular is normal, but opportunities are scarce. Not everyone can have their turn. If one blindly chases this, they'll surely lose themselves.
The only thing to persist in is to continuously increase one's strength.
Just quietly work hard, and then amaze everybody.
