Ookami Shoujo to Kuro Ouji

Erika Shinohara has spent too much time inventing stories about a boyfriend she does not have, all to keep up with her new friends. When they demand proof, she photographs a handsome stranger and claims he is hers, only to discover that the boy is Kyouya Sata, one of the most popular students at her own school.

Kyouya agrees to play the perfect boyfriend in public, but privately he reveals a cruel, teasing side and demands that Erika behave like his obedient "dog" in exchange for protecting her lie. The arrangement should be unbearable, yet time together exposes sides of Kyouya that no one else sees. Erika's fake romance begins producing very real feelings, leaving her trapped by the one lie she can no longer simply laugh away.
