High school girl Erika may be on Kyoya’s leash, but she’s determined to break free and unleash his heart!

Fed up with her friends’ constant bragging about their boyfriends, high school student Erika Shinohara decides to make up a relationship of her own. When her lie starts unravelling at the seams, her charming schoolmate Kyoya Sata agrees to be her pretend boyfriend, seemingly saving her reputation. She won’t get off that easy, however, as she soon discovers her white knight is actually a blackhearted prince! Now Erika must be at his beck and call or risk her lie being exposed. But is Kyoya really as blackhearted as he seems?

When Sata learns Erika gifted Kusakabe the same homemade sweet she offered him, he loses it—and the pair’s days as a pretend couple are over! Complicating matters, Kusakabe asks Erika out for White Day. Erika knows she’d be happy with the kindhearted Kusakabe, but is she ready to drop Kyoya for good?
