In one of Rose's songs, I don't know what it was called, I think "On the ground" she admits she really didn't have to sell out because she realizes everything she needs is...on the ground.
I thought the meaning of the song was a bit different. Many people mistake it for a love song but she's actually speaking to her younger self who was more naive and innocent to the world, that's why you see young rose wearing white (purity, innocence) and blackpink rose (wearing black and pink) have a brief interaction in the MV
She already sold out, so her saying that she
"realizes" that everything she needs is
"on the ground", the ground refers to the earth, is saying that she realizes that everything she's ever dreamed and chased after since she was young (fame, stardom) is on earth and she will continue to strive for earthly desires.
The bible clearly says to keep away from worldly or earthly things (and if I recall correctly I heard that her and her family is chrisitian even though you can't really be a christian and be in that demonic industry) so either she doesn't practice the religion anymore or she's lying but off-topic)
Colossians 3:2-
Set your minds on things that are above, not on things that are on earth.
James 4:4
You adulterous people! Do you not know that friendship with the world is enmity with God? Therefore whoever wishes to be a friend of the world makes himself an enemy of God.
So since the ground is referring to earth in her song, and she's speaking to her younger self in the song, she says at first
"I worked my whole life just to get right, just be like, look at me I'm never coming down" meaning that she was brought up in the christian faith by her family to work hard and do the right thing. It could also mean her referring to young trainee Rose, who entered the industry not knowing much and just working hard to reach her goal. But she also says in the song
Funny when you want it, suddenly you have it, You find out that your gold's just plastic meaning that the promise of becoming a star as a trainee was granted, as her and her group are one of the biggest kpop girl groups right now, but she realized as she got higher up, fame and stardom is all just a fake illusion she was working hard for and comes with a price (losing your soul) and whatever her group had to do to reach that level of success.
"Yeah what goes up, it must come down" is a metaphor of Newton's law of motion to stardom... as she climbs higher and higher to success and stardom on earth, she most eventually come down... meaning hell, hence why there is fire all around her in a certain scene as she surrounded by theater shows
which contrasts to her inncoent younger self, enclosed in a room with musical instruments (practicing to become a musician) and wearing the same fur like coat, but more softer. Satan doesn't give things for free and in the end she will pay the price of fame and choosing the "ground" (earth) which is why her younger self, or her right conscious warns her in the song
"you're running out of time" meaning it will all eventually come to an end once Jesus will come again soon during the second resurrection and she will be judged for her choices and how she decided to spend her God given gifts on earth, which she chose to selfishly for herself by serving the devil and deceiving many.
