The ability to speak gives a great opportunity to express one"s thoughts and feelings, to share them with someone. This ability truly makes a person happy. But words can hurt, cause unbearable pain. Words spoken in anger, in an outburst of uncontrollable rage, and words that had no intention to offend… Life teaches us to be restrained in our expressions, but unfortunately not everyone heeds the idiom "keep your tongue behind your teeth."
Once Joon was happy. But she was too young to understand the simple truth: not only actions can harm anyone. A few words, and her family was destroyed. And that was all her fault. Yet from nowhere a tiny spirit in the form of a funny egg appears before the girl, and magically seals her voice so that Joon can never again cause someone suffering.
Thus, from now on silent but with a heart tormented by bitterness, in the shadow of her own alienation, she continues to live and grow up. Until one day luck extends its warm palm to her, and, firmly taking the girl by the hand, leads her out of the darkness of regret into blinding light, toward people whose power can change her. Joon suddenly realizes that happiness was close by, and that a wounded heart—such a small heart—so desperately wants to cry.
