@kiyorisu_ayanon, this is a pretty easy question, and there are many possible answers. The most common ones are: they just got bored and grew up, they simply have more worries in real life, or something like that. Or they simply lost interest in writing. I haven’t watched or read COTE for a long time. Sometimes I check here, on this website, to see if there’s a continuation of interesting stories or if something new has come out that’s really interesting. I’m currently in Turkey, dealing with my educational documents from Russia so I can enroll in a university in Turkey. I’m learning Turkish, working online, and taking care of my health, as quite a lot of nonsense has accumulated. In short, it’s only natural. Over the more than 5 years I’ve been in this fandom, many people have left and joined. It’s sad, really, but it can’t be avoided.
