Do you know how confident I am in my writing for a somewhat fan-fic? Mad confident. Like even if my writing was a level lower, it would still be much better than more than half of the original works/fan-fictions.
Stability? Pffft. If I can't think of something original, there is always that cliche plot which most people seem to find as a guilty pleasure, so you'll be fine!
Story development? Lol please, read the first chapter and tell me do you get the usual flashback of the "I met God by dying on the way home by truck-kun and yadadada," no.
