this is alright, the ML is a stereotypical ML but the MC is annoying. He has the meng thing going on as a kitten but once the story progresses it becomes more and more obvious that there's a pit where his brain should be.
Spoiler
instead of taking his situation seriously, even when his life is in danger, he's more interested in finding a way for his tiny body to somehow top the ML, as he's fixated on being a gong. He's far more concerned with that than with what's actually happening around him and doesn't seem to care at all about why he's there, nor does he try to figure out what he's supposed to do.
he has to be threatened with shaving, (a fate worse than annihilation apparently), to do even the simplest system tasks. He's clueless about the world he created and is constantly surprised by basic elements within it despite being the author. He also has no sense of danger, is impulsive and very careless, leading to him becoming a typical damsel in distress over and over again.
he hasn't used the knowledge of the plot much at all so him being a writer with a goldfinger (foreknowledge) is as useless as the rest of him ATM. He just lets things happen to himself rather than using his knowledge, which is baffling for me; why would he not use his advantages? Someone else commented that unlike some MC he doesn't lose IQ once together with the ML but as of ch 25, I would argue that he doesn't have much IQ to lose in the first place.
I stopped reading at chapter 25 due to the MC and to the messier than usual MTL (which keeps changing the name of the MC and ML and never once uses their actual names. I.e the ML is 'the cars broken face/broken edge of the car/broken edge/broken car/cars/broken/etc.' it's different almost every time). I might try again if this gets translated but maybe not; I have a low tolerance threshold for this kind of MC, rating it a 3 is already at my limit.
