Twisted Devotion

Delinquent Tanaka is feared by all and nicknamed the Mad Dog. He fought every day, and rumors and whispers about him filled the school halls. That is, until a gloomy-looking, ordinary girl in glasses suddenly appeared. She didn't fear him, but rather, everything she did got on Tanaka's nerves. "The way your face twists with emotion is very, very cute." The unique air about her captures and traps Tanaka in her twisted cage.
