Just like all the other stories from this author, the rating isn't deserved since almost all of the reviews are just alt accounts of theirs.
The writing quality: and grammar are not the best. I guess it's readable but you will often find yourself scratching your head wondering what exactly is going on in the story and why certain characters are behaving the way they are.
Stability of updates: is the only thing I can confidently give his a five on seeing as the author at least updates their stories frequently.
story development: as previously mentioned can be very confusing. it's an interesting concept for sure, but the writing is so poorly executed and scenes are so poorly set up that you'll often just find yourself wondering if you missed a chapter or something.
Character design: the author claims the mc is naïve but in actuality she's just an idiot. she doesn't understand basic social cues at all apparently. even after 6 years she still can't tell a person doesn't like someone else after they get upset each time she brings their name up.
world background: granted I haven't read all the chapters, but from what I could read, there isn't much.
overall, I understand the grind, but the author has a very bad habit of overinflating the rating for their novels.
