It’s a typical day. The tram is filled with people going to work or going to school. Everyone is staring at their phones. It seems like nothing could pull them out of those tiny screens. A boy sits quietly. Step by step, the sleepy creeper crawled into his mind. It gradually becomes hard for him to open his eyes. He tries his best to open his eyes and look around. All of the other people are grey and playing with their phones. When he is almost fallen asleep, a pair of red ballet shoes appear in front of him. It is incredible to see something colorful in this grey world.

​

The owner of the red ballet shoes is a girl. Her skin looks so transient that it can reflect the light. She dances in this crowded tram-like no one is here. When she touches a person, that guy will immediately put down the phone. At the same time, a mysterious white light gradually covers the whole tram. There is no limit any more: sakura from nowhere floats in the air, trees grow up near the train, and unknown flowers blossom everywhere. Butterflies, birds, small animals also join in this party. The boy is shocked. He sees people get color on them. A piece of sakura lands on his nose, he finds himself becoming colorful, too.

​

However, everything will come to an end. When the girl leaves, everything is back to the way it was. The boy blinks his big eyes, and then a large smile appears on his face. Now he is also the colorful one in this grey world.
