This was a chapter where the author lamented the state of popularity of the fanfic while affirming that they're bad at writing, which is BS in my opinion. Compared to other Chinese fanfics I've read, this is a masterpiece. I cried a few times while reading this, and Munchlax is one of the cutest creatures ever conceived in fiction, so I don't buy it.
You don't have to worry about the author dropping this; this fanfic is completed, and we're nowhere near the end.
The Author also thanked a few supporters.
