there are a LOT of things you can speculate about regarding what twsa was actually like as a novel but what's most interesting to me is that you can make the argument that twsa was an "unpolished" version of what orv is. it's a version of a similar novel that likely dealt with a lot of similar themes but was seemingly bogged down by poor structure, pacing, expository handling, and focus. (all of which are things that orv is shockingly excellent at.)
and of course, han sooyoung's novel, sssss-grade infinite regressor, is the "polished" version of the idea. it's well-written, probably well-plotted, and was successful enough to make han sooyoung rich and famous. we don't know what sssss-grade infinite regressor is like as a novel either, but we sort of get the impression that it's not very emotionally rich even if it is good on a technical level. han sooyoung herself doesn't seem intensely attached to it despite being proud of her work, and kim dokja of course doesn't hold it in high regard. (though of course he's a gigantic unreliable narrator and also a hater.)
what's interesting is that despite orv very strongly emphasizing the ways these works are flawed from the outset, orv itself functions as an argument in these works' favor. both twsa and infinite regressor are stand-ins for the "mass-produced" genre of webnovels. they are popular fiction, relying on a very familiar pool of tropes and clichés in order to deliver on a relatively predictable story to appeal to a wide audience. it's not a coincidence that they are so similar - both literally and in a meta sense, they are drawing on the same exact story-building and genre material. twsa is just the unsuccessful version, and infinite regressor is the successful one.
orv is what I would consider the most "impressive" version of the genre. it's well-structured, thrillingly plotted, interestingly written, has fascinating ideas and characters, and is even "literary" - that is, it has deeply considered themes and is often drawing from the realm of literary, postmodern fiction in order to express its ideas. a less sincere story would disavow itself from its pop-fiction origins and claim to be the best version of its genre. nothing else could be like it, so the worst versions of its genre wouldn't be worth considering.
but orv, while technically functioning as an argument that the genre can be "good" simply because it's a great novel that is deeply rooted in its genre, goes much further. it argues in-text that any sort of story, even those that are bad on a technical level or those that were somewhat cynically produced for a mass audience, are worth finding value in, simply because stories have meaning to their readers. the most uncritical reproduction of a genre's conventions can still mean something to someone who likes it. twsa, if it existed in our reality, would still probably be considered a very bad novel, but it wouldn't need to be polished up and turned into infinite regressor or orv in order to have value. orv itself is telling you that you should find value in twsa as it is, and by extension, every badly-done work of fiction that twsa could be a stand-in for!
