I saw a tiktok about a hero finding the code for the villains safe and no one knows how he did it. He knew it cause it was tattooed on the villains thighs. Sooo, I was like I need a book where the hero and villain are together and they hide their relationship. It could be that they got together halfway or in the start or before the book begins. I would love if the mc is female. And it has to have moments of them hiding their relationship and people suspecting it. Thanks
