The author commented that the fanfiction is for himself but as he writes, it is apparent that this claim is false. If the fanfiction was for himself, why would he need to explain his story direction mid-chapter? Why is there voting for story direction? The grammar is pretty bad at times, and for a majority of what I read, he refers to the MC, as well MC. Or when he introduces the MC's parents, he does so as MC's dad or MC's mom. And then explains why it would be easier to just call them Mom or Dad instead of MC.
All in all, the plot has plenty of potential. But I do believe the author needs to iron how to convey that potential
