Back when she was a kid, Marica has always been bullied. Kids at her age often makes fun of her—almost like villains pretending to be in kids body just to cause pain to others. Even so, Marica never showed her tears—even if she's under a great anger or a thirst of fighting back, until one day, when she was about to give in, a chubby little boy came and saved her. He was brave and yet somehow stupid. He is small and yet he is so strong. Kids who bullied her fear him and yet she adores him. Due to that scenario, they became friends, friends closer than two magnets glued together. It was fun. They were happy but as the saying goes by, "even a life itself has it ends", Marica needed to leave. She needed to leave the place she grew up with—including the person who made her grow even better. Before they separate from each other—with wide and yet sad smile, Marica promised to that boy that she'll comeback. Of course, she will and she did. But then, when Marica came back, the boy she played with when she was kid was no longer to be found.
