Lindsay Brown started a TikTok page dedicated entirely to telling her weird and slightly creepy love story with none other than her stepbrother. Lindsey and Cade started seeing each other when they were just 14 years old - and not related.
Their parents also fell in love with each other and eventually got married, making them officially brother and sister. "So, no. Our parents didn't get married before us. We did it first. We didn't do anything wrong," Lindsey said. "I married my stepbrother and I don't think we did anything wrong"
