Sometimes, everyone needs something to rely on for relief from stress in the real world, or maybe just a break from school or work. Sometimes, planning on writing long novels just piles onto the work and anxiety people can have. For me at least, I can pour out every single idea for one topic, and of course, it won't always last for multiple chapters. They give me a sense of relief I guess, and it can also become a longer piece work as well. It all depends on each person ^^
