Maybe...but with him mentioning his constant time restraints balancing a wife, kid's as well working a demanding full time job. As you mentioned, and he stated a few times back in 2020, 2021...as well only making about $300-$500 per month for all his long hours, taking away his free time away from his family creating story content.
It's sad that it's over, and understandable...as it would become a choice that the family would comes first. Also doesn't help with many of the past reviewers back then nit piking and bitched about his efforts with the last chapter of his story. It will be missed.
Regards.
Like Tyrranus said, though, this isn't
maybe conjecture. You could say it's "educated" conjecture if you want, but it's still just that: conjecture. You have evidence of a
possible reality, but
no proof of what actually is. That, by definition, is conjecture. Nobody knows what's happened. If it makes you feel better at night, you can believe whatever you want. But all the theorizing — even based on information like you have — is still not proof of things. So in case anybody else reads in this thread to see what's happened,
here is the actual answer: Nobody knows. Nobody will ever know unless Kyois makes an official statement explaining. That's it.
