Two best friends Chocolat and Vanilla are both candidates for the next Queen of the magical world. For the Queenship competition, they are assigned with a task to collect “hearts” -crystallized feelings of love- from human boys. The one who ends up with more hearts wins the battle and becomes the next Queen.

As soon as they start their lives in the human world, Chocolat finds herself fighting against odds. Turns out human boys prefer timid Vanilla to self-assertive Chocolat. Will Chocolat be able to learn how to make human boys fall in love with her?
