I Became My Fiancé's Accessory [Book Transmigration]

Transmigrating into a book was bad enough, but worse still, she became a cannon-fodder female supporting character. And not just any cannon fodder, but a character so minor she was practically a nobody. Not only was she a nobody, she was a nobody hopelessly in love with the villain. Wasn't that a guaranteed death sentence? The little fox spirit Hu Yao decides to save herself. She doesn't have the guts to break off the engagement, but she can enter a marriage of convenience. :) But on the very first day she announces she's going to enter a marriage of convenience, she transmigrates into a button on her fiancé's shirt. Hu Yao: ...What a great body. Now I regret it. The "I never wanted this" feeling comes on way too fast. Hu Yao starts spending her days transmigrating into all kinds of accessories. And, you know, practicing cultivation does get easier when she's following her fiancé around. But! I don't want to transmigrate into underwear!!! No, no, no! Underwear is definitely out of the question! Message: A lively and optimistic outlook on love
