When you read a story and it ends short you are left hanging you are disappointed
When you read a story and it ends long even the problems has been resolved you are still disappointed
you've already lived through the story every main character is a friend every nemesis is an enemy of your own you wanted to see every characters story but your time is not enough the story has been too long it must end
stories even when short or prolonged endings even when hanging or solved still leaves a sad longing at the end
