Your Heart Is My Enemy is the story of a love triangle between anger and kindness. He aids her his help to kindly help her home and was a friend to her--a friend who was kind and polite toward her as well as others. An angel. Meanwhile, him, he made her suffer hell by suggesting they'd go out and stole something from her. Something precious. What was it? Who did Aikawa choose? The kind-hearted or temper-issued? What was the hell that she endured?
