Is my roommate a caged bird? I'm stealing her away.

The female lead is materialistic, very realistic, has flaws, and is somewhat vulgar.
My roommate is kept by that Mr. Chen; she carries designer bags and uses expensive creams.
Zhou Suisui looked at herself in the mirror again and again—she wasn't as pretty as me.
She schemed and plotted, and finally became his woman. But instead of replacing her roommate, she became his sister.
Until she overheard Chen Boxu sneer at his friend outside the club:
"Zhou Suisui? Just a way to kill time."
"She's even greedier than her roommate; this kind of woman is the easiest to deal with."
Is it unpleasant to listen to? Yes, it is.
But Chen Boxu was right about one thing—she was indeed greedy.
They coveted his money, the lifestyle he provided, and even more so, the next person who could offer an even higher price.
Since in his eyes, they are all commodities with clearly marked prices.
All she had to do was get rid of him/her.
Find someone richer and better than him.
