arachnodroid is really good for having been written when I was 11-12 actually. baby me did a fantastic job of characterizing renasa.
you literally watch him become Like That as throughout the diary entries he talks more and more like “the world is against me” until he’s literally a grown 43 year old still obsessed with getting the last laugh at the high school science club of 28 years ago.
