I'm The Prince's Beard Beard

In the novel Amy is reading, her favorite BL-Fanfic-writer-turned-author kills the only gay representative?
How dare the author do that, forgetting all about the BL fanfic roots from which they came?
But all of a sudden, in best isekai-style Amy is INSIDE the novel and decides to save the prince and his gay ass!
But how will Amy manage when she suck at proper etiquette, doesn't have any BL books, and can't have pant-less days eating chips?

Just to be clear, a "beard" is slang for a woman either dating or marrying a gay man to make him seem not-gay
