Kookmin/Jikook oneshots

Help

Hi I just wanted to vent or get some opinions. As you guys know one of my one shots is about the red string of fate AU. I recently saw that someone had copied my idea of Jungkook not having a soulmate or a strong but still dating jimin. Idk what to do. They did copied my idea but they added some extra plot to make their ff longer. I should talk with them about it and resolve the issue but I'm scared to do that. They have a higher fan following than me. Their readers might cause issues for me. Similar things have happened to me multiple times and everytime I was forced to delete my books because of false reports. I've been on this site since even before they had a professional team. The head of the administration team isn't a fan of me because we have argued about the false reports. I can't ask help from wattpad. Idk what to do.
