Transmigrated as the Betrothed of the Yandere Villain

Zhong Ning transmigrated into a book and became a cannon fodder character who, due to being outrageously arrogant and abusive towards the villain, ended up having her legs broken, her voice poisoned mute, locked away in a room, and spent the rest of her life dependent on others to care for her—ultimately dying in a fire at the sanatorium. — Description from novelcodex.org
