I'll level with you, I only read the first chapter - all 67 pages of it. My irreconcilable issues are with the abysmal pacing, lack of conflict, and the passive main character. Also, your pitch betrays a lack of confidence in your own writing which I find distasteful. To make matters worse, you did not give a plot synopsis, which is not doing yourself any favors.
The milquetoast MC - an aimless low achiever and prime NEET candidate is a poor choice of viewpoint character. He is reactive and more importantly, seems rather disinterested from the literal impossibility of transforming into a Nekomimi. 67 pages for an intro that fails to establish our main character, his capabilities, or even the stakes of the fiction is unacceptable. Hell my copy of A Witch Shall be Born establishes conflict, core cast, and locale in 12 pages flat.
The work has definite pacing issues. Over 67 pages to detail the dull minutiae of our MC's banal morning routing - literally wake, eat, and bitch about his life. Then he randomly gets transformed into a cute cat girl, handwaving the TF sequence and coping with physical changes - omitting the main draw of TF stories. He then buys clothing and is adopted by his boss circumventing all possible tension of being homeless, coping with his new ID, and again - the draw of TF stories being the slow burn descent into the new persona...
At this point I'm not sure of your target audience or genre. It does not appear to be fans of TF or mind-break, and H is ruled out with the glacial pacing. You spent so many words to say absolutely nothing of substance. I mean your average paperback would be nearing the climax at this point!
I would ask that you reconsider the purpose of the work and reupload after heavy edits, trimming the fat and getting to the real content. Have you considered the serial novel format? Tailored to maximize the medium with smaller but more frequent uploads. It might help to focus your efforts. I hope you take my words into account and look forward to more of your content.
