A little confused is there more after side story 4?? Since it says tbc?

sometimes short stories are left with a open ending like that so authors can come back later if they want to continue the story and make it longer, as of rn the story is officially completed. I've seen a few other stories do that where they did end up making them a lot longer then they were at first but I've also seen them stay as is and never get more chapters, just depends on what the author wants to do with the short story
