Shinsouban Heart no Kuni no Alice: Wonderful Wonder World

Alice is realistic; especially about love. One day, she is taken to the world of heart, which is full of danger. For example, an owner of a hat shop is a gangster, and every theme park worker carries a gun; almost all of the people are dangerous. She somehow starts to enjoy her life there, after she is forced to take a drug which prevents her from returning to her original world. Will she find a way back? Will she fall in love?
