I saw this earlier, and immediately thought of Ruby. If only someone would actually tell her that.
If she has any common sense, she'd have seen the red flags in her agent. She rushed to sign Ruby based on a complete mess of a first draft with no interesting concept, terrible writing and paper-thin characters. Almost no agent would touch a rough first draft, especially with the quality of writing and ideas that Ruby has to offer. Then her agent markets the book using her fake influencer name more prominently than the plot. Ruby's agent clearly only signed her for her name, not her writing.
Her agent also doesn't appear very successful, and the few sales she's had are to tiny independent publishers or one owned by/with direct ties to the literary agency, so that doesn't bode well for Ruby.
If Ruby genuinely wanted to succeed based on the quality of her writing, she'd have ditched the fake influencer name or used another wildly different pseudonym, never mentioned her writing on social media and slogged it out like any other writer would. But Ruby doesn't want to work at anything and her egotistical brain will twist any easy reward based on her privilege as a reflection of how special and gifted she is.
And she also clearly doesn't actually want to write or enjoy it. She's just chasing fame and fortune by choosing the closest profession she can think of to fit her fake bookworm persona and chose to write in the most marketable genre she could think of despite disliking YA fiction.
I don't think she's remotely prepared for the onslought of rejection she's going to get from publishers though. Her best case scenario is a tiny book deal from a publisher nobody's ever heard of, which she only got for her name and for which she'll receive almost nothing. That reality isn't going to sit well with Ruby and her dreams of massive literary success, £1million advances and movie adaptations.
