I'm trying to find this manhwa where the fl got isekaid/reincarnated in a bl story(?) and she was pretending to be a man to survive and he became a duke. She has white/gray hair and I remember that the prince is in love with her (he doesn't know he's a girl). The fl was friends with the prince's sister because she found out that the princess is actually someone who remembers her past life and got isekaid to the story too. They have this plan to make the story progress and have the fl act like a perfect male lead(?). i think the bottom in the original story fell inlove with the female lead.
