I just want to say - I feel this so hard. Especially last year, when I submitted a short story to the Webtoons contest, which was only four episodes (so a five minute, ten minute tops, read) and I later learned that some of my friends didn't even read it, after being all "supportive." I don't really expect most of my friends to keep up with my ongoing webtoon, but the fact that some of them didn't read my short story even after I told them that it was also very personal and their views/support might help my standing in the contest, really felt like it put a dent in our friendship. I just didn't feel like I could trust them anymore because anything they said was insincere.
I am probably taking it too personally, but as someone who has a really hard time sharing my art with people IRL to begin with, it definitely hurt.
