Ookami Shoujo to Kuro Ouji

Wolf Girl & Black Prince follows Erika Shinohara, a girl who has been lying about her romantic life to earn the respect of her new friends. When they ask for a photo of her boyfriend, she hastily snaps one of a handsome stranger, only to discover that he is Kyouya Sata, a popular classmate admired for his kindness and good looks. Desperate to keep her lie from falling apart, Erika asks Kyouya to pretend to be her boyfriend. He agrees, but only after revealing a cruel streak that is very different from the image he shows everyone else, and he begins treating Erika like his "dog" in exchange for protecting her secret. Forced into that humiliating arrangement, Erika keeps encountering the real Kyouya beneath his polished exterior. As she spends more time with him, her feelings become harder to ignore, and the balance between embarrassment, blackmail, and genuine affection starts to shift. Erika must decide whether a relationship built on lies can become something honest before her deception catches up with her.
