If you came here for a JP-like fluffy, comedy, slice-of-life novel about a random dude living with a hot elf, then look no further, cause that's exactly what you'll get....... for a couple of chapters - and then it'll go all in on grim-dark despair.
Overall, Elf-story (shortform for this novel's long ass title), is really well written. It has good humor, narration, exposition, pacing, witty dialogue, and multi-dimensional characters with fleshed out backgrounds.
So, all's well that ends well?
Unfortunately, and this is my personal opinion, the story just got too dark too quickly - and theres too much of it without any sunshine (read:fluff/romance/light heartedness/happy moments/etc). This, combined with a beta, spineless, and indecisive MC (who we never get to know the name of), simply began to annoy me more and more.
I came here for a fluffy elf-chan comedy story, then I was pleasantly surprised with deeper and darker plot, but then it became tedious reading about a never evolving relationship, pitifully spineless MC, and constant dark-upon-dark developments, where the story is going from one crisis to another.
I hope that in the future plot can include some more romance, where Ash (elf-chan) and MC kiss, make up, do gf+bf stuff - and no, don't tear them apart with some stupid deus-ex machina plot machinations the next chapter to prove their love or some other random bullshit reasoning. Keep them together, and have them develop together for the fluff in the dark.
In short, fluff is good, but lately too much dark and crisis combined with a constantly spineless MC is becoming tedious to read.
