"Erika talks to her friends about boyfriends and romance, but in all her 16 years she's never actually had one. One day she takes a secret video of a guy in town and brags that he's her boyfriend.
His name is Kyoya Sata and he's just transferred to her school. When she owns up to her lie and offers to clear the air, it turns out that under his sweet exterior, he's actually a malicious sadist."
