It was in the modern era and the protagonist was a webnovel author. No suggestion that the protagonist had a system/reincarnated/transmigrated. I guess it is part fantasy since he appears to inherit the skills of the dead novelist but he himself is unaware of this. Example was his current novel was garbage but once he had the dead man belonging (laptop, glassess, cat) he was able to revise it within hours and earned the praises of his editor who previously despaired of his poor skills. He then went on to write a whole book worth in less than a day (a martial art novel) and the editor called to say they wanted to publish it and suggested they continue with new story arcs
There wasn't any particular defining physical trait. Only other main thing I can remember was he went to college to become a writer - all his fellow students had gone on to do others jobs except for one who did become a successful novelist who looked down on the MC.
I read it on an aggregator site I believe. I don't keep any bookmarks and tried to search with keywords but not successful
