With witty details in every corner of the picture, the book develops an interesting story as if watching an animation. Meet our imaginations through a book, which we might have done once. This is a secret story between the two that goes beyond the competition. An interesting story we might have imagined at least once was realized in a picture book. The story has been dramatically described from Ji-Ahn and her sister\'s running game to having their secret. Recalling the artist\'s childhood, she captured the memories with her older sister in a secret story. A web-based picture book was written by planning cute characters, arranging playful typography, and drawing realistic scenes. The three-dimensional production of the web-based picture book is also a charming point that cannot be missed. ● Author Introduction JI AHN SOHN She graduated from the Affinity Universe Design School and has been drawing web design pictures.
