Orange Bubble Gum

Yoo-i is a very special girl -- she's like refreshing and fragrant orange bubble gums.. A boy appears all of a sudden and becomes a natural part of her life, as natural as breathing air.. His name is Joo-in. He says, "Do you know nuna? Nuna is. my past, my present, and my future.. You are like this ladder connecting me to this world.." (Source: Wataame Shoujo)
