The Five Worlds

“A,B,C,D,E,F,G...H,I,J,K,L,M,N.....” You are singing the ABC song in order to not get bored, your horrible voice attracts a couple; Beautiful blond haired girl with a handsome curly haired boy. They leap towards you as they are holding hands, bright smiles appear on their faces. "You have a terrible voice, but that's ok," the girl says. ''We are here to give you a riddle, if you answer this right, we will lead you to the kingdom of Uranus, but if you get it wrong, something bad will happened to you," the boy says. You are quite nervous because their joyful smiles disappear, they look very sober.
The boy starts:

"What I want is your heart
it is like a fragile piece of art
imagine the time with you
it will be like a dream came true
we might holding hands
till our lives ends
we might be kissing
our mind will be missing
spending the rest of our times
counting the wrinkle lines"
"Now you have to choose your answer," the girl says.
