A lot of what Jing is saying is eerily in tune with Ji's reincarnation and path moving forward.
"You may have gotten lucky this time, that you landed a chance to perform solo yet again"
"As long as your issues remain unresolved, your solo performances will ultimately amount to nothing, no matter how moving they may be"
"You may have a 'next time', but others might not be so lucky"
It's like she's indirectly talking to Ji. And Ji having gotten lucky in this next life is finally working to resolve her issues, acting more proactive/confident, and has way thicker skin. She won't waste her chance this time.
The parallels are a little nuttier knowing that both Ji and Ningwei died in the og timeline. So it really is make it or break it for them in more ways than one.
