I mean… easiest way to tackle this is to name the novel and let us judge.
In all seriousness though. Going viral has precious little to do with quality. It all boils down to luck. I do cosplay, I have a set of LED eyes that I have full control over, I can emote so well I put a vtuber to shame, and this is real life before your eyes. I’ll run around as the black mage from ff1
Took 5 years to go viral on Twitter and get an article written on adafruit. Go to any con and you’ll see comics and books trying to sell out of booths. Have you ever purchased one on a whim? Or do you just walk by?

like I legit won best performance in Daishocon back in 2017. You would THINK “oh that’s totally when cosplayers and propmakers would see it and go nuts” but no. The tweet that went viral was just some rando (with a very racy/bdsm following as well if I remember right) who just did a drive by recording of me (without even asking). Didn’t even know the guys name.
